A Guide to Getting Started with R

1 Getting Acqainted with R

1.1 Using R as a giant calculator

Produce a sequence of numbers:

seq(from = 0,
    to = 10, 
    by = 1) #interval 
##  [1]  0  1  2  3  4  5  6  7  8  9 10

1.2 Your first script

Creating objects:

x<-seq(from = 0, to = 10, by =0.5)
x
##  [1]  0.0  0.5  1.0  1.5  2.0  2.5  3.0  3.5  4.0  4.5  5.0  5.5  6.0  6.5  7.0
## [16]  7.5  8.0  8.5  9.0  9.5 10.0
y<-seq(from = 101, to = 110, by =0.5)

Add the objects together to create a new object:

z <- x + y  
## Warning in x + y: longer object length is not a multiple of shorter object
## length
z
##  [1] 101.0 102.0 103.0 104.0 105.0 106.0 107.0 108.0 109.0 110.0 111.0 112.0
## [13] 113.0 114.0 115.0 116.0 117.0 118.0 119.0 110.5 111.5
