error using Corpus in R (wordcloud)

Question

I am new to R and trying wordcloud using a text file separated by spaces. I have installed tm and tmap packages. I am getting following errors:

Error: could not find function "Corpus"
Error: could not find function "tm_map"

Can anybody help me out ?

Answer 1

You have to load the packages also into your session via

library(tm)
library(tmap)

Then the function tm() is available for you. Another possibilty is

tm::tm_map()

This calls R to take the function tm_map() from package tm .

Answer 2

I tried after installing below and it worked for me:

install.packages("http://cran.r-project.org/bin/windows/contrib/3.0/tm_0.5-10.zip",repos=NULL)
library(tm)
