Dear R users,
I have a dataframe that contains several variables, among which 105
correspond to scores on certain trials. Unfortunately, when I imported this
dataframe into R, I realised that the variable names corresponding to each
trial begin with digits, which violates R naming conventions.
I am trying to relabel these variables by adding a 'v' as a prefix to each
of them, I'd like to use tidyverse, but I am struggling with this process
of renaming. When I run this chunk of code, no error occurs but my
variables are not renamed. I'm fairly new to R and I can't understand what
I'm doing wrong.
```{r}
behavioral_df <- behavioral_df %>% rename_with(.fn = ~paste0("v"),
starts_with('^\\d'))
```
You should also consider not renaming the columns. R allows
non-standard names to be used as long as you quote them somehow. For
example,
behavioral_df[, "50%"]
will get you the column with name "50%", as will
behavioral_df$`50%`
I suspect most tidyverse functions will be fine with the `50%` style of
quoting.
