Replace column values in R conditional on values from different column
...but instead every cell has values in it, except for the
initial NAs. I think R somehow inserted 0 instead of NAs for the gender
values which were not supposed to be in that column (i.e. replaced values
for females with 0 in the male column) but I don't know why.
Thanks!!!!!
for(i in 1:length(Health2$CohenSum)){
if (Health2$q_5a[i]==1) Health2$CohenM[i] <- Health2$CohenSum[i]
else if (Health2$q_5a[i]==2) Health2$CohenF[i] <- Health2$CohenSum[i]
else Health2$CohenF[i] <- NA
}

Keep rows in a dataset if one value in a column is duplicated
...or atomic vectors". I am
just beginning to learn R, so I apologize if the code is really rough.
Basically I want to keep all the rows in the data set for which the value of
"Pairiddups" is TRUE. How do I do it? And how do I get past the error?
Thank you so much,
Diana
