问题
I want to add a suffix to a group of columns in a data set (CTDB). For example I have the following columns and I would like to add "_Child" to the end.
This subset is part of a larger dataset with 100+ columns, and I do not want to re-write every single column name.
[9] "SCARED_BREATHE"
[10] "SCARED_HEADACHE_SCHOOL"

I have tried the following code but I get the following error.
> colnames(CTDB[,c(BREATHE_SCARED:ENJOY_PRAISE)]) <- paste(colnames(CTDB[,c(BREATHE_SCARED:ENJOY_PRAISE)]), "CHILD", sep = "_")
Error in check_names_df(j, x) : object 'BREATHE_SCARED' not found
Thank you for your help!
回答1:
Depending on your data, this could work:
colnames(CTDB)[9:83] <- paste(colnames(CTDB)[9:83], "CHILD", sep = "_")
If you don't want to set the indices manually, you can use "which()" to find them.
回答2:
CTDB %>% rename_at(BREATHE_SCARED:ENJOY_PRAISE, ~paste0(., "_Child"))
