Getting Started with R

Some Commands

read.table(filename,header=TRUE)           # Read tab or space delimited file with a header
read.table(filename,header=TRUE,sep=',')   # Read csv files with a header

v1 <- c(1,2,3,4,5,6,7)                     # Create a vector from these values
v2 <- c(1:10)                              # Create a vector from 1 to 10

v3 <- c(v1,v2)                             # Concatenate the vectors

matrix1 <- cbind(v1,v2)                    # Column bind into a 2 x n matrix

ls                                         # List objects
