read.table或read.csv无法加载其数据

Question

I'm in trouble with importing csv data to R. csv is large scale of log data which has 50culumns and few million lines including header. I have 15 files and load some of them make issue.

data<-read.table("1.csv",header=T,sep=',', stringsAsFactors = F, fill = T)

After that code, in usual 1.csv loaded to 'data' or give warning if 1.csv has problem. But in my case, nothing happen. After loading, there are no message and there is no object named 'data'.

is anyone experienced like this?

Answer 1

Check this :

library(data.table)
fread('1.csv', header = T, sep = ',')

It's more efficient than read.table and maybe this is the main problem
