Rename the columns of your dm
using syntax that is similar to dplyr::rename()
.
Arguments
- dm
A
dm
object.- table
A table in the
dm
.- ...
One or more unquoted expressions separated by commas. You can treat variable names as if they were positions, and use expressions like
x:y
to select the ranges of variables.Use named arguments, e.g.
new_name = old_name
, to rename the selected variables.The arguments in ... are automatically quoted and evaluated in a context where column names represent column positions. They also support unquoting and splicing. See
vignette("programming", package = "dplyr")
for an introduction to those concepts.See select helpers for more details, and the examples about tidyselect helpers, such as
starts_with()
,everything()
, etc.
