[R] coerce data.frame with table-like data to a table for use with barchart.table
I have a data.frame containing survey data that is already organized like a table:> fooExcellent Very Good Good Fair Poor Very Poor Question 1 8 7 3 0 0 0 Question 2 5 5 7 1 0 0 Question 3 7 10 1 0 0 0> class(foo)[1] "data.frame">I would like to make a barchart (or stripplot) with three barcharts, one for each row in the data.frame foo. It seems like I have to coerce foo to class table to use with barchart.table in lattice but a simple as.table yields no fruit. Any help appreciated.

Dear Dr. Carbon,
Perhaps (not lattice):
barplot(t(foo),beside=TRUE,col=rainbow(6),ylim=c(0,max(foo)),names.arg=paste('Question',1:3),
ylab='Your title here',xlab='Your title here')
legend('topleft',colnames(foo),pch=15,col=rainbow(6),ncol=2,cex=1.1)
HTH,
Jorge
