title: R tm package will not load to R studio
body: <p>I have been trying to load the tm text mining package onto R studio for a number of hours now. I have tried everything I have come across online but it doesnt appear to work. 
  I started with </p>
  
  <pre><code>install.packages('tm', dependencies = TRUE)
  </code></pre>
  
  <p>and am given the following error </p>
  
  <pre><code>Installing package into ‘D:/Users/byrne/Documents/R/win-library/3.2’
  (as ‘lib’ is unspecified)
  Warning in install.packages :
    dependencies ‘slam’, ‘Rcampdf’, ‘Rgraphviz’, ‘Rpoppler’, ‘tm.lexicon.GeneralInquirer’ are not available
  trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.2/tm_0.6-2.zip'
  Content type 'application/zip' length 710948 bytes (694 KB)
  downloaded 694 KB
  </code></pre>
  
  <p>when i then try to load the package using </p>
  
  <pre><code>library(tm)
  </code></pre>
  
  <p>I get this error </p>
  
  <pre><code>Loading required package: NLP
  Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) : 
    there is no package called ‘slam’
  Error: package or namespace load failed for ‘tm’
  </code></pre>
  
  <p>I have then loaded NLP and tried to load 'slam'. which  it then tells me is not available on R version 3.2.3. I then updated to 3.2.5 and it still gives me the same message. I have changed the CRAN mirror to mutliple different locations and still get the same error. </p>
  
  <p>Any help is greatly appreciated as I'm stumped now. </p>
