You haven't shown us what you did, but it looks like you tried to
replace the names of an object with a vector (of length 1199) when a
vector of length 17 was required. See this example:
dat <- as.data.frame(matrix(rnorm(100), ncol = 10))
names(dat) <- LETTERS[1:10]
names(dat)
[1] "A" "B" "C" "D" "E" "F" "G" "H" "I" "J"
names(dat) <- LETTERS
Error in `names<-.default`(`*tmp*`, value = c("A", "B", "C", "D", "E", :
'names' attribute [26] must be the same length as the vector [10]
Where I have tried to replace names(dat) (which should be of length 10)
with a vector of length 26 (all the letters A-Z).
The error message above is not the same as the one you show though, so
this might not be the problem. As the posting guide asks, please give a
reproducible example or provide enough information for us to help you.
