Two-way tabulation

Description

Two-way tabulation with automatic mosaic plot

Usage

tabpct (row, col, ..., decimal = 1, percent = c("both", "col", "row"), 
graph = TRUE, las = 0)  

Arguments

row, col variables
... additional arguments for 'table'
decimal number of decimals for the percentage in the table
percent orientation of the percentage in the table
graph automatic graphing
las orientation of group labelling,
0: always parallel to axis
1: always horizontal,
2: always perpendicular to the axis,
3: always vertical.

Details

'tabpct' gives column and row percent cross-tabulation as well as mosaic plot.

The width of the bar in the plot denotes the relative proportion of the row variable.

Inside each bar, the relative proportion denotes the distribution of column variables within each row variable.

Note that 'row' and 'col' arguments of this function are for the table, not the mosaic plot and the default value for the 'percent' orientation is "both".

Value

Tables of row and column percentage

Examples

data(Oswego)
.data <- Oswego
attach(.data)

# The above commands generate a data frame. 
# In reality, one just exploits 'use("Oswego.rec")', if the file is available.
agegr <- cut(age, breaks=c(0,20,40,60,80))
label.var(agegr, "age group")
tabpct(agegr, ill)
