问题
I am trying to create a Total sum column that adds up the values of the previous columns. However I am having difficulty if there is an NA. If there is an NA in the row, my script will not calculate the sum.
How do I edit the following script to essentially count the NA's as 0, or just ignore them completely but still calculate the sum. I don't want to actually change the NA to 0.
CTDB %>% mutate(SCARED_TOTAL_CHILD = CTDB %>% rowwise() %>%
SELECT(SCARED_BREATHE_CHILD:SCARED_SHY_CHILD) %>% rowSums()) -> CTDB
Thank you!!
回答1:
Add in na.rm=TRUE
i.e
rowSums(na.rm=TRUE)
回答2:
ummm, I think the help for the function outlines how to omit NAs from the calc.... try
rowSums(.,na.rm=T)
