R Missing Redshift Package?

[katerina_newton]

Hi All,

Just wanted to let you know that when I first tried connecting through R, it produced the following error so it looks like the Redshift package needs to be installed separately. The Instructure slides we were following didn't include that step and it created some confusion among our group. Just thought I'd share this info in case others were having the same problem.

require(redshift)

Loading required package: redshift

Warning message:

In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE,  :

  there is no package called ‘redshift’

Good tip Katarina.  Thanks!  I will make sure to point this out next time I demo R connectivity.

Hi Matt, sorry to bug you constantly Happy Friday! So I tried to install the redshift package for R from here: CRAN - Package devtools

And it's giving me this error. What version of Java do I need to have in order for this to load properly?

* installing *source* package 'redshift' ...

** R

** inst

** preparing package for lazy loading

Error : .onLoad failed in loadNamespace() for 'rJava', details:

  call: fun(libname, pkgname)

  error: No CurrentVersion entry in Software/JavaSoft registry! Try re-installing Java and make sure R and Java have matching architectures.

Error : package 'rJava' could not be loaded

ERROR: lazy loading failed for package 'redshift'

* removing 'C:/Program Files/R/R-3.2.0/library/redshift'

Error: Command failed (1)

Matt, you can disregard it. I was running a 64-bit version of R and 32-bit Java, so I installed 64-bit Java and was able to install the package just fine

* installing *source* package 'redshift' ...

** R

** inst

** preparing package for lazy loading

** help

*** installing help indices

** building package indices

** testing if installed package can be loaded
