R : Reading data from CSV file

To read data from a csv file, you can use the use the read.table function in R:

> myData <- read.table("C:/Downloads/R_Tutorial/18MarchStudentInfo.csv", header=TRUE, sep=",")
The above command assumes your csv file has a header field at the begining of the file describing the column names. If your CSV does not contain a row describing the column names you can use it as :

> mydata <- read.table("C:/Downloads/R_Tutorial/18MarchStudentInfo.csv", header=FALSE, sep=",")
Change sep field appropriately depending on your column delimiter in your CSV
