I'm sorry! Now I tried it again with just 10 numbers (just random numbers) and Excel gives a different output than R.
Here are the numbers I used: 0,2006160108532920 0,1321167173880490 0,0563941428921262 0,0264198664609803 0,0200581303857603 -0,2971754213679500 -0,2353086361784190 0,0667195538296534 0,1755852636926560 And this is the command in R: > nums <- as.numeric(as.character(dataSet2$ac_bhar_60d_4d_after_ann[2:10])) > m <- mean(nums, na.rm = T) > m The output of R is: > print(m, digits= 12) [1] 0.0166666666667 The output in Excel is: 0,0161584031062386 The numbers are imported correctly. Or does R reduce the imported numbers to any decimal place? (i don't think so ;-) ) Best Regards, Felix -- View this message in context: http://r.789695.n4.nabble.com/Calculating-the-mean-in-one-column-with-empty-cells-tp4645135p4645165.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
