I have a table like this:
counts[1:4,]
aaa 0.0010 -0.0252 -0.0039
aac 0.0452 0.0168 -0.0238
aag -0.0117 -0.0029 0.0400
aat 0.0301 0.0248 0.0070
I want to make a bar plot, where the three columns for each row are next to each other, and the name for that three numbers are labeled by the row name. I have no problem when plotting three rows:
barplot(counts[1:3,], col=c("red","lightblue","gray"), beside = T, names=row.names(counts)[1:3])
But when I plot the four rows (or more), R complains about the number of names is incorrect:
"Error in barplot.default(counts[1:4, ], col = c("red", "lightblue", "gray"), :
incorrect number of names"
barplot(counts[1:4,], col=c("red","lightblue","gray"), beside = T, las=3, names.arg=row.names(counts)[1:4])
How can i plot these groups with one name for each group?
