Hi welcome to the forum.
I do not sure what the problem is but you have one extra character in the first vector. delay35 versus delay3
Otherwise we need a bit more information
See FAQ: How to do a minimal reproducible example ( reprex ) for beginners
A handy way to supply some sample data is the dput() function. In the case of a large dataset something like dput(head(mydata, 100)) should supply the data we need. Just do dput(mydata) where mydata is your data. Copy the output and paste it here.
