# R -- Introduction & Programming Codes

- R functions (
`rcnorm` and
`rcnorm`*i* (*i*=1,2,3,4,5)) to generate
contaminated normal random variates and `cpu.time`
(function to compute CPU time of evaluating an expression) can be found
in rcnorm.R.
- R functions used to produce probability density plot with shading
for selected distributions are in
pdfShading.R.
- An R function used to simulate coefficients and error in linear
regression can be found in
lmSimu1.R.
- R for Simulation by Examples
simu2013mar.R.
Also, 2 R functions for confidence intervals:
bs.R.
