Hi', welcome to the forum.
IT is rather difficult to work from screenshots and we rather discourage their use. See FAQ Asking Questions
It looks like {tidyverse} is successfully installed now. If you are using tinytex
I believe it does this automatically.
If I am reading this correctly I think you want
filter(dat_non_NA, reykir = "ja" & bmi > 25)
If not, would you supply us with your code and some sample data?
A handy way to supply some sample data is the dput() function. In the case of a large dataset something like dput(head(mydata, 100)) should supply the data we need. Just do dput(mydata) where mydata is your data. Copy the output and paste it here.
Thanks
