Hi there,
I have a question on how to read a bunch of dataset, assign each of the
dataset to a matrix in the memory, and append them.
Suppose I have 20 dataset saved to different .rda files named gradeFileData1,
gradeFileData2,...., gradeFileData20. And I would like to read them each into a
dataset in the memory, then combine them. I wrote something like:
e1<-new.env(parent=.GlobalEnv)
maxi <- 20
i <- 1
while (i<=maxi) {
e1$d <-1
datanam <- paste("data",i,sep="")
data <- e1$d
names(data)[length(data)] <- datanam
i <- i+1
}
The function "names(data)[length(data)]" doesn't seem to work. I need it to be
named like data1,data2,,,,,data20.....
Also to append them into a big dataset, I think there should be something
simpler than
all <- rbind(data1,data2,data3,data4,data5,data6,data7,data8.........data20)
can you help me on this? I hope this is not some simplest R question..... I am
a beginner.
Thanks a ton!
Grace
