如何将读取的数据帧另存为R中的列表？

Question

I have say about 10 .txt files in my directory that I read like this:

sampleFiles <- list.files(directory)
for (i in 1:length(sampleFiles)) {
 table <- read.table( sampleFiles[i], header = TRUE)
}

I want to store the read file such that I can access them as table1 for i=1 , table2 for i=2 and tablen for i=n . How can I read all these files and save as dataframe base names table ?

Answer 1

Use lapply

Data <- lapply( list.files(directory), read.table, header=TRUE)

In order to access each data.frame you can use [[ as in Data[[1]] , Data[[2]] ,..., Data[[n]]

Answer 2

To name them as you describe, replace the table <- assignment in your loop with

assign(paste0("table", j), read.table(sampleFiles[j], header = TRUE))

Your question title is slightly misleading, as this is not saving the tables as a list in the formal R sense of a list (for which, see the other answer).
