Subject: Error: arguments imply differing number of rows
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
