Dear R users,
in the example below the name of the genus will be displayed in the main
titles using the variable predictor[i] and paste.
I would like to have the genus name in italic. However all my attempts
using expression and substitute failed.
Does anybody know a solution?
Thanks a lot in advance. bernd
Acrobeles <-c(65.1,0.0,0.0,0.0,0.0,0.0)
Acrobeloides <-c(0.0,9.8,76.7,51.1,93.9,43.9)
Alaimus <-c(0.0,4.9,0.0,0.0,0.0,6.3)
Aphelenchoides <-c(126.5,29.3,76.7,134.1,176.7,87.9)
x<-data.frame(Acrobeles,Acrobeloides,Alaimus,Aphelenchoides)
predictor <- colnames(x)
ylabel <-"Numerical abundance"
mainlabel1 <-"Boxplot for"
mainlabel2 <-"sp."
cexalabel <-1.8 # axis label
cexmlabel <-1.6 # main label
par(oma=c(6,6,3,3),mar = c(6, 4, 4, 2) + 0.1,mfrow=c(2,2))
for (i in 1:ncol(x)){
boxplot(x[,i],
main=paste(mainlabel,predictor[i],mainlabel2),ylab=paste(ylabel),cex.lab=cexalabel,cex.main=cexmlabel,cex.axis=1.5)
}
