Hi, the first command was bringing the numbers into R directly: *> testdata <- c(0.2006160108532920, 0.1321167173880490, 0.0563941428921262, 0.0264198664609803, 0.0200581303857603, -0.2971754213679500, -0.2353086361784190, 0.0667195538296534, 0.1755852636926560)
mean(testdata)
[1] 0.0161584* Here I tried to calculate the mean with the same numbers as given above, but taken from my dataset. *
str(dataSet2$ac_bhar_60d_4d_after_ann[1:9])
num [1:9] 0.2 0.13 0.06 0.03 0.02 -0.3 -0.24 0.07 0.18
mean(dataSet2$ac_bhar_60d_4d_after_ann[1:9])
[1] 0.01666667 * It seems that in the second case he calculates the mean with rounded numbers (0.2 and not 0.20061601085...) Could it be that R imports only the rounded numbers? How can I build a CSV-file with numbers showing all decimal places? Because I think my current CSV-file only has numbers with 2 decimal places.
That's something you need to figure out with whatever software is writing the csv. Cheers, Michael
