[R] Is 'temp' a reserved/key word in R?

[Sarah Goslee]

Andrew is right - it's a typo.

More broadly, there's no restriction of that sort on the contents of
your data frame - reserved words can't be used for object names. The R
Language Definition is the best resource for identifying those words.

It would help if you provided the package for read_csv, since not
everyone uses tidyverse by default, although it isn't necessary for
this question.
