Hello,
I have a data frame:
> dim(tot)
[1] 502536 1093
How would I extract from it all strings that start with E10?
I know how to extract all rows that contain with E10
df0<-tot %>% filter_all(any_vars(. %in% c('E10')))
> dim(df0)
[1] 5105 1093
but I just need a vector of strings that start with E10...
it would look something like this:
[1] "E102" "E109" "E108" "E103" "E104" "E105" "E101" "E106" "E107"
Thanks
Ana
