Package ztable

Introduction

Table Show

Package “ztable” make everything possible about table. Basically, An object of “ztable” made from a data.frame. The default output format of ztable is RStudio::viewer or web-browser format(type=“viewer”). So if you want to use ztable in a “html” format, you should change the parameter ztable.type to “html”. If you want to use ztable in latex format, you should change the parameter ztable.type to “latex”.

library(ztable)
library(magrittr)
options(ztable.type="html")
z=ztable(head(iris))
z

5 5.00 3.60 1.40 0.20 setosa
6 5.40 3.90 1.70 0.40 setosa

You can change the position of data in each cell by adjusting the parameter “align”.

z=ztable(head(iris),align="cccccc")
z

5 5.00 3.60 1.40 0.20 setosa
6 5.40 3.90 1.70 0.40 setosa

You can change background color and font color with addRowColor() function.

z <- ztable(head(iris))
z <- addRowColor(z, rows=1,bg="#C90000",color="white") 
print(z)

The pipe operator(“%>%”) from magrittr package can simplify your R code.

ztable(head(iris)) %>%
    addRowColor(rows=1,bg="#C90000",color="white") %>%
    print

5 5.00 3.60 1.40 0.20 setosa
6 5.40 3.90 1.70 0.40 setosa

You can add column groups to ztable using addcgroup function. The n.cgroup means how much columns included in each row group.

cgroup=c("Sepal","Petal","Species")
n.cgroup=c(2,2,1)
z <- ztable(head(iris)) %>%
    addcgroup(cgroup=cgroup,n.cgroup=n.cgroup)
z

6 5.40 3.90 1.70 0.40 setosa

You can add row groups to ztable using addrgroup function. The n.rgroup means how much rows included in each row group. The cspan.rgroup means how much columns occupied by row group name.

rgroup=c("OneToThree","Four","FiveToSix")
n.rgroup=c(3,1,2)

z <- z %>% 
    addrgroup(rgroup=rgroup,n.rgroup=n.rgroup,cspan.rgroup=1)

print(z,type="latex")

You can add another colname(subcolname), the N count for example. The length of subcolnames should be same with column count of data.frame. You can use “NA” and the column name spans 2 rows.

ncount=c(123,120,123,124)
sub=paste("(N=",ncount,")",sep="")
z=addSubColNames(z,c(sub,NA))

z=spanRow(z,col=3,from=5,to=7,"platinum","blue")

Please note that if you add vertical lines between groups, the space between groups(empty columns) disappeared and vice versa.

Merge two tables

You can bind two or more data.frame by cbind function.

t1=head(iris,10)[,c(1,3,5)]
t2=tail(iris,10)[,c(1,3,5)]
t=cbind(t1,t2)
z=ztable(t,caption="Table 1. Top 10 and Last 10 Data from iris",align="ccccccc")
z

10 4.90 1.50 setosa 5.90 5.10 virginica

And then, you can add column groups, row groups, add row colors, add column colors, add cell colors, and merge cells

cgroup=c("Top 10","Last 10")
n.cgroup=c(3,3)
z=addcgroup(z,cgroup=cgroup,n.cgroup=n.cgroup)

Basic Use

Package “ztable” consist of one function: ztable. It’s main function is creating zebra zebra striping tables(tables with alternating row colors) in both Latex and html formats easily from mainly data.frame or an R object such as matrix, lm, aov, anova, glm and coxph objects. It is fully customizable and you can get similar tables in both latex and html format without changing source. The default output is RStudio::viewer, but you can get html format by adding just one sentence.

options(ztable.type="html")

It’s usage is somewhat similar to xtable, but very simple.

data.frame

Basic Use

It’s use is very simple. Just use ‘ztable()’ function. You can get the zebra striping table by set the parameter zebra=1 (default value is NULL)

require(ztable)
options(ztable.type="html")
options(ztable.zebra=1)
options(ztable.zebra.color="platinum")
options(ztable.colnames.bold=TRUE)

Tailoring zebra striping

You can get non-zebra table by change parameter zebra=NULL or change zebra striping on even rows by zebra=2.

Customize the caption and the font size

You can change the position of table by using parameter position. You can use “r” for right position, “l” for left position and “c” for center position(default). You can change the color of zebra striping by change the parameter zebra.color. You can also change the size of font from 1 to 10(default is 5). You can change the caption.placement(“top” or “bottom”) and caption.position(“c” for center / “r” for right/ “l” for left).

ztable(head(mtcars[c(1:7)]),zebra=2,zebra.color="lightcyan",size=7,

aov object

‘ztable()’ can be used for ‘aov’ object. When used for ‘aov’ object, the function call is added as footer to the table. The parameter ‘show.footer’ can be used whether or not include footer in the table. Default value is TRUE.

Customize the zebra striping colors

If you wanted to use several colors for zebra striping, you can set the parameter ‘zebra’ to zero(e.g. zebra=0) and set the ‘zebra.color’ parameter with vector of your favorite colors. Your favorite colors are used to zebra striping. For your convienience, ten colors are predifned for this purpose. The predefined colors are: c(“peach”,“peach-orange”,“peachpuff”,“peach-yellow”,“pear”,“pearl”,“peridot”,“periwinkle”,“pastelred”, “pastelgray”).

Place two or more ztables or figures side by side

If you wanted to place two or more ztables or figures side by side, you can use function parallelTables(). Function parallelTables() takes three parameters. The first parameter width is a numeric vector specifies the width to which the tables or figures should be scaled. The second parameter is a list of ztable or names of valid figure. The 3rd parameter ‘type’ is the type of table to produce. Possible values for type are “latex” or “html”. Default value is “latex”. See the examples.

z=ztable(head(mtcars[1:3]),tabular=TRUE,zebra.color="peach-orange")
z1=ztable(head(iris[1:3]),tabular=TRUE,zebra=2)
