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?
Thanks,
Carol
