Error: arguments imply differing number of rows
Try str() on both objects and see what you get. It
does not look like you have two vectors of
length=1762.
See this for example
=====================================================
aa <- c("A", "B", "D", "D","B", "B","D", "A", "C",
"C", "A","D")
bb <- rnorm(length(aa))
cc <- matrix(rnorm(length(aa)),nrow=2)
length(bb)
length(cc)
boxplot(bb~aa)
boxplot(cc~aa)
======================================================

I am simply trying to put 4 boxplots on the same plot, but I keep getting the "arguments imply differing number of rows" error. Here, I have two variables: a factor x of length 1762 (with 4 levels) and a numeric variable y of length 1762. How is it that my arguments imply differing numbers of rows?
length(x)
[1] 1762
length(y)
[1] 1762
is.factor(x)
[1] TRUE
is.numeric(y)
[1] TRUE
plot(x,y)
Error in data.frame(group, x) : arguments imply differing number of rows: 1762, 2165
boxplot(y~x)
Error in data.frame(group, x) : arguments imply differing number of rows: 1762, 2165
