Dealing with missing values in princomp (package "psych")
Hello!
I am running principle components analysis using princomp function in
pacakge psych.
mypc <- princomp(mydataforpc, cor=TRUE)
Question: I'd like to use pairwise deletion of missing cases when
correlations are calculated. I.e., I'd like to have a correlation between
any 2 variables to be based on all cases that have valid values on both
variables.
What should my na.action be in this case?
Thank you ve...
