I have a data frame with some columns being logical. I wanted to calculate a column that is an AND combination of the other logical columns. I tried to use apply(df,1,all) It did not work because of the implicit string conversion. So I made the functions All<-function(...) all(as.logical(...))#because all cannot be used with apply Any<-function(...) any(as.logical(...))#because any cannot be used with apply Now apply(df,1,All) seemed to work, but produced some NAs where there was no reason for them. I debugged apply and found that some logical values are transformed to " TRUE" instead of "TRUE". I did not follow that up closer. Instead I worked around it by doing the string conversion myself and then call apply(dfc,1,All) ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-devel
