Hi all,I am trying to create a barplot for the following data: ssmsm, ssaudmn, sstacmn .35, .93, .63 1.9, 1.51., 1.8 .78, 1.6, 1.24 1.10, 1.60, 1.24 I used the following code: sd<-read.table("dat.csv", header=T, sep=",") barplot(as.matrix(sd), main="Figure 1", ylab= "Mean", beside=TRUE, col=rainbow(3)) legend("topleft", c("low", "chronic", "remitted", "late-onset"), cex=0.6, bty="n", fill=rainbow(3)) But I get the following error: Error in -0.01 * height : non-numeric argument to binary operator I get that sd needs to be a matrix, but I'm not sure why using as.matrix is not good enough. Any suggestions?
