Hi to everybody,
i have a little problem with some values:
when I type:
tmp <- read.table("tottimecourse.txt", sep="\t", header=T,
na.strings = "")
some data appear with "NA" value.....:
[232] -1.64 -0.98 -0.48 -2.18 -0.41 0.07 0.03 NA -1.17 -0.70
-1.80
-0.95 -0.74 -0.66 -0.33 NA NA NA NA NA NA
[253] NA NA NA NA NA NA NA NA -0.65 0.84
-0.59
0.01 -0.16 -0.71 NA NA NA NA NA NA NA
[274] NA NA NA NA NA NA NA NA NA NA N
how can i apply a function in order to transfor "NA" with 0 ?
best wishes
