If data set A only has the months January through to October, while data set B only has the months April – November, is there a way to filter my data to only… Read More If I have two groups in my data which partially match for a second categorical variable, is there a way to remove non-matching groups?
I’m trying to count the number of NA values in each of 2 columns. The code below works. temp2 %>% select(c18basic, c18ipug) %>% summarise_all(funs(sum(is.na(.)))) But I get this warning: Warning message: `funs()` was deprecated in dplyr 0.8.0.

I would like to calculate growth rates across rows by groups (here groups are "country" and "year") in a dataset that is in the long format. Since the growth rate should be relative to the same value (i.e., same "country" and same "year") under the "Baseline" scenario (not relative to the previous row), I am… Read More Calculating growth rates across rows by groups in the long format (relative to a base group) in R
I’m having trouble getting r’s dplyr::arrange() to sort properly when used in a for loop. I found many posts discussing this issue (like ex.1 with the .by_group=TRUE and using desc() bettter, ex.2 with lists, and ex.3 with filter_all() and %in%). Yet, I’m still having a bit of trouble understanding why I can get the arrange()… Read More Why doesn't R dplyr arrange sort properly using a vector element within a for loop
