Are you looking for a complete list of R keywords or a specific keyword?

for a complete list of R keywords
OK, I found some sources that provide a complete list of R keywords.

One source is 2, which lists the following keywords:

if
else
repeat
while
function
for
in
next
break
TRUE
FALSE
NULL
Inf
NaN
NA
NA_integer_
NA_real_
NA_complex_
NA_character_
Another source is 2, which suggests using the following command to get the list of valid keywords:

#列出关键字的命令是：
ls (asNamespace ("base"), all.names=TRUE)

或者终端命令行输入：

help(reserved)    ## 或
?reserved

I hope this helps.
Do you have any other questions about R keywords?
