read.csv() - two out of three columns
12,293
You can use the colClasses
argument to skip columns:
mydata <- read.csv('mydata.csv', colClasses=c('NULL',NA,NA))
or
mydata <- read.csv('mydata.csv', colClasses=c('NULL', 'numeric', 'numeric'))

Only read limited number of columns in RI have a ascii-dataset which consists of three columns, but only the last two are actual data. Now I want to dotchart the data by using
read.csv(file = "result1", sep= " ")
. R reads all three columns. How do I avoid this?
