Re: [R] How Can I Execute a String Expression?

R is not a very good macro language... I recommend against this strategy. We could be more concrete in offering alternatives if you were a little more complete in your reproducible example [1][2][3]. What variations exactly were you thinking of? What kind of data are you working with? The way

Re: [R] replacement has *** rows, data has ***

This can happen if there are rows containing missing values (NA's) in the data used to fit the model. Use na.action=na.exclude when fitting the model instead of the default na.action=na.omit to make the prediction vector line up with the input data instead of lining up with the input data after

Hi all, I created a predicted variable based on a model, but somehow not all observations have a predicted value. When I tired to add the predicated value to the main data set (data$pr <- pr) , it said: replacement has 34333 rows, data has 34347. Do you know how to solve that? Thanks, Manqing
