Hi I am trying to create a column in a data frame which gives a sigificane score from 0-7. It should read values from 7 different colums and add 1 to the counter if the value is <=0.05. I get an error message saying
Error in if (ALLRESULTS[i, 16] <= 0.05) significance_count = significance_count + : missing value where TRUE/FALSE needed The script is included below it works if i convert the NA values to zero but this is not appropriate as it includes the zero as significant. ANY SUGGESTIONS #SCRIPT STARTS for (i in 1:length(ALLRESULTS[,1])) { significance_count = 0 if (ALLRESULTS[i,16] <= 0.05 ) significance_count = significance_count +1 else significance_count = significance_count if (ALLRESULTS[i,17] <= 0.05 ) significance_count = significance_count +1 else significance_count = significance_count if (ALLRESULTS[i,18] <= 0.05 ) significance_count = significance_count +1 else significance_count = significance_count if (ALLRESULTS[i,19] <= 0.05 ) significance_count = significance_count +1 else significance_count = significance_count if (ALLRESULTS[i,20] <= 0.05 ) significance_count = significance_count +1 else significance_count = significance_count if (ALLRESULTS[i,21] <= 0.05 ) significance_count = significance_count +1 else significance_count = significance_count if (ALLRESULTS[i,22] <= 0.05 ) significance_count = significance_count +1 else significance_count = significance_count ALLRESULTS[i,23] <- significance_count} ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
