Hi Marcos,
I'd be glad to help, but your example is not usable for anyone but
yourself - I don't have the files that your code reads and I don't have
any idea what the resulting data frames look like. Please provide
examples of the data and the result.

rm(list=ls())
# loadEcgFiles <- function(Dir=".") {
Dir <- ".";
txtfiles <- list.files(paste(Dir),'.txt$');
ecg = data.frame(ncol=1);
len = length(txtfiles);
for (i in 1:5 ) {
# i <- 1;
filename = paste(projectDir, "/" ,
txtfiles[i],sep='');
sample = read.table(filename, nrow=75000);
sampleName = filename; sampleName=gsub("./",
"",sampleName); sampleName=gsub(".txt", "", sampleName);
temp <- sample$V2;
names(temp) <- sampleName;
ecg = cbind(ecg, temp);
# }
