Hello,
Also note that the index to datalist should be i + 1, 0 is not an
allowed index number.
datalist[[i + 1]] <- read.table(...)
Hope this helps,

Hello r-community,
my name is philipp and i´m studying economics at the university of bonn.
I´m writing a paper about an experimental entry game and need help to write a
for loop.
for (i in 0:7) {
data <- read.table("~/Uni/SoSe
13/Bachelorarbeit/entryGameAnalysis/analysis/data/23.04.13...10H/GROUP0/0/history.txt",
sep="\t" , header=TRUE, blank.lines.skip=TRUE, strip.white = TRUE)
data[5]
}
the goal is to read column 5 of the history.txt for GROUP0/0,
GROUP0/1,…..GROUP0/7.
Something along these lines (and do note that your current arrangement would
overwrite the previous file with each iteration and executing data[5] would
have done nothing, since no assignment was made):
datalist<-list()
for (i in 0:7) {
datalist[[i]] <- read.table(file=paste0("~/Uni/SoSe
13/Bachelorarbeit/entryGameAnalysis/analysis/data/23.04.13...10H/GROUP0/",i,"/history.txt"),
sep="\t" , header=TRUE, blank.lines.skip=TRUE, strip.white = TRUE, colClasses=c(rep(NULL,4),
"character",rep(NULL,1000))
}
Using colClasses to extract only the 5th column.
