dependency ‘slam’ is not available when installing

Question

I was able to use the library(tm) in r without problem until today, when loading tm shows:

library(tm)

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’

I thought this is a dependency issue and seek to reinstall package

install.packages("tm")

Warning in install.packages : dependency ‘slam’ is not available

and then try to find slam:

install.packages("slam")

Warning in install.packages :

package ‘slam’ is not available (for R version 3.2.4)

I also tried some of the issues listed here and chooseCRANmirror(), still no luck. Is there something wrong with the package or is it just that my r does not allow 'slam' to install after today?

Answer 1

I had the same problem and:

• I upgraded RStudio to the latest version (1.0.143)
• I upgraded R to the latest version (R.3.3.3)
• I rebooted Rstudio
• I installed again in RStudio the package "tm"
• I ran library(tm)

and everything works fine now.

Answer 2

I found a hint at this german site about R under Install additional R packages ("Zusätzliche R-Pakete installieren") After I installed slam seperatly over apt-get for example:

sudo apt-get install r-cran-slam

I could install tm the normal way:

install.packages('tm')

And load the library aswell.

I hope my answer helps someone.

Answer 3

1. Just Install NLP package with dependencies = True

2. Install tm packaged with dependencies = True

And things should work out:)

Answer 4

I used the following code to install the binary or the older version of slam. It worked for me.

install.packages("slam", type = "binary")

Answer 5

I am using R3.2.5. I was trying to install "tm". I did install NLP as a dependency but gave me an error :

"package ‘slam’ is not available (for R version 3.2.5)"

The option I had to was to download the zip/tar/gz file(binaries) from https://cran.r-project.org/web/packages/slam/index.html and install the package. It worked for me after that. Although I am not sure what the problem is because the library information mentions it is for R (≥ 3.3.1)

Answer 6

I also had to upgrade to the most recent version of R.

Specifically, on Ubuntu 16.04 here are instructions to get the up to date R version.
