r - How to read the data from web -
i import data http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/regression/mg r. dataset contains 1,385 data points featuring 6 independent variables , 1 dependent variable. how can import data file r?
i suppose looking read.table
:
read.table("http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/regression/mg")
if want remove column numbers , colons numeric values, can use gsub
:
dat <- read.table("http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/regression/mg", stringsasfactors = false) dat[-1] <- lapply(dat[-1], function(x) as.numeric(gsub(".:", "", x)))
