This is vector not list.

which is probably data frame

I do not know rstudio but you could check two objects by
?identical

I wonder why do you use as.numeric in the first instance. You coud use

auxs1 <- unlist(csv1[1,])
and you should get named numeric vector. Maybe there are problems when reading numbers from csv file. You could check it e.g. by

str(auxs1)
