  • 0

I am developing a R package in Eclipse. Although I am new to this environment, it’s been great.

But one problem I am facing is that after running R CMD install after check and build in Eclipse, if I type in R console of Eclipse,

library(mypackagename)
?mypackagename

Eclipse still displays old help. I’ve already tried restarting, rebooting, and so on in vain. If I run R in windows, it displays correct help for the package. I wonder what is going on.

I suspect Eclipse has its own cache for R help but can’t find how to delete it.

Update As seen in @JimM’s answer, you should select following to update R help.

"R console View menu" -> R environment -> Index completely

This will take 2-3 mins but I found there is no other way to update R help.

    If you’re using the StatET plug-in, there’s a couple of ways to update the R environment.

    First, To update the R environment manually, in the Console window in the StatET perspective, there’s a downward facing triangle in the top right corner. If you click and hold the triangle, there is the option under the R environment to either “Index completely” or “Index changes”. If you choose to “Index completely”, it will rebuild the entire R Index/Help cache.

    Alternatively, under Preferences > StatET > Run/Debug > R Environments, there’s an option to update the R Environment index to “Check and Update Automatically”.
