coltable: Color the cells of a data frame according to 2 threshold levels

Description

Return a colored display of a data frame according to 2 threshold levels.

Usage

coltable(matrice,nbrow=nrow(matrice),nbcol=ncol(matrice),level.lower=0.05,col.lower="mistyrose",level.upper=1e10,col.upper="lightblue",cex=0,nbdec=4,main.title=NULL)

Arguments

matrice

a data frame (or a matrix) with only quantitative variables

nbrow

the number of rows to be displayed (by default, nrow(matrice))

nbcol

the number of columns to be displayed (by default, ncol(matrice))

level.lower

the threshold below which cells are colored in col.lower

col.lower

the color used for level.lower

level.upper

the threshold above which cells are colored in col.upper

col.upper

the color used for level.upper

cex

cf. function par in the graphics package

nbdec

the number of decimal places displayed

main.title

title of the graph(s)

Details

This function is very useful especially when there are a lot of values to check.

Examples

## Example 1
data(chocolates)
resdecat<-decat(chocolates,formul="~Product+Panelist",firstvar=5,graph=FALSE)
coltable(magicsort(resdecat$tabT),level.lower=-1.96,level.upper=1.96,main.title="Products' description")

## Example 2
data(chocolates)
resaverage<-averagetable(chocolates,formul="~Product+Panelist",firstvar=5)
coltable(magicsort(resaverage),level.upper=6,level.lower=4,main.title="Average by chocolate")

## Example 3
data(chocolates)
resperf<-paneliperf(chocolates,formul="~Product+Panelist+Product:Panelist",formul.j="~Product",col.j=1,firstvar=5,lastvar=12,synthesis=FALSE,graph=FALSE)
resperfprob<-magicsort(resperf$prob.ind,method="median")
coltable(resperfprob,level.lower=0.05,level.upper=1,main.title="P-value of the F-test (by panelist)")

resperfr2<-magicsort(resperf$r2.ind,method="median",ascending=FALSE)
coltable(resperfr2,level.lower=0.00,level.upper=0.85,main.title="Adjusted R-square (by panelist)")
