missing package

[Nathan Pace]

I have installed RRO 3.2.1.

I need to use a package (ggExtra) with update 2015-07-13.

Running RRO, I installed ggExtra.

In my Rmd file, I set

library(checkpoint)

setSnapshot('2015-07-20')

I checked that ggExtra was in MRAN at that date.

Yet:

> library(ggExtra)

Error in library(ggExtra) : there is no package called ‘ggExtra’

Unable to debug this problem.

Hello Nathan,

Perhaps someone will weigh in with a better answer, but I believe you should use:

library(checkpoint) checkpoint("2015-07-20")

Let me know if that works for you. If not, I'll investigate further.

I actually did it first with the checkpoint function.

I just ran it again.

major    3  

minor    2.1

I also get a warning message about not reaching MRAN.

In my Rmd file, there is a call for ggExtra

library(ggExtra).

I ran installed.packages()

ggExtra is not returned.

Hi Nathan,

Thanks for your report. 

You can install packages from a current version of CRAN, or any MRAN snapshot.  I'd like to be sure you have the latest version of checkpoint, 0.3.10.

Try this to update checkpoint to the current version on CRAN:

install.packages("checkpoint", repos = c(CRAN = "cran.revolutionanalytics.com"))

After updating to the latest, could you please open a clean session of R, then tell me the results of:

library("checkpoint")
sessionInfo()

We'll investigate further on our end as well.

Thank you,

Josée

Hello Nathan,

Try the following:

library(checkpoint)

# Install ggExtra from latest CRAN mirror 

install.packages("ggExtra", repos = "https://cran.revolutionanalytics.com/")

library(ggExtra)

# Confirm you've loaded version 0.2.0 of that package.

sessionInfo()

Thanks,

Josée

Closing/Opening my project  and running same checkpoint code with 2015-07-20 has resolved the problem.

ggExtra 0.2.0 is now installed.

Glad to hear it has worked itself out, Nathan.
