Hello!
Here is a toy tibble problem:
xt <-
tibble(x=LETTERS[1:4],y=1:4,z=rnorm(4),a=c("dog","cat","tree","ferret"))
str(xt)
Classes ‘tbl_df’, ‘tbl’ and 'data.frame': 4 obs. of 4 variables:
$ x: chr "A" "B" "C" "D"
$ y: int 1 2 3 4
$ z: num 0.3246 0.0504 0.339 0.4872
$ a: chr "dog" "cat" "tree" "ferret"
#No surprise
xt %>% mean
[1] NA
Warning message:
In mean.default(.) : argument is not numeric or logical: returning NA
#surprised!
mean(xt[2:3])
[1] NA
Warning message:
In mean.default(xt[2:3]) : argument is not numeric or logical: returning NA
xt[, 2:3] %>% mean
[1] NA
Warning message:
In mean.default(.) : argument is not numeric or logical: returning NA
I have a feeling that I'm doing something silly wrong. Has anyone run into
this, please? I saw something like this on this list, but didn't see a
solution.
Thanks,
Erin
