Error: package or namespace load failed for ‘QuantumClone’

[andhena]

Dear Paul,
I would like to use QuantumClone but I'm experiencing troubles with making it work.
Indeed when I do:
> install.packages("QuantumClone")
There is no error but once I try to load it using
> library(QuantumClone)
Then I got this error
Error: package or namespace load failed for ‘QuantumClone’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]): there is no package called ‘robustbase’
I've tried to download robustbase independently but the error is persisting.
Coud you please help me with this problem?
Thank you in advance,
Kind regards, -Charlotte

NB: I'm using R version 3.4.4

Hi Charlotte,

Are you running on Unix or Windows?
I tried to reproduce on Windows 8, R 3.5.0 with the CRAN and Github versions but could not get your error.

Can you check that robustbase is installed correctly? (either with find.package("robustbase") or by loading it with library(robustbase) ). Could you do the same for fpc too?

fpc imports robustbase to initialize cluster centers, if you use the k-medoid initialization. A quick fix would be to move to fpcto suggested packages and not imports, but would not directly solve your issue.

Best wishes,

Hi Paul,
I'm using Mac OS X (El Capitan, v 10.11.5) and I guess that's why it's not working.
I've made some research and found an interesting discussion so I'm gonna share it here in case someone using a Mac has a similar problem :

But it didn't work for me so I used biocLite instead:

source("https://bioconductor.org/biocLite.R")
biocLite()
biocLite("robustbase")
biocLite("kernlab")

I never experienced that kind of troubles installing R packages but at least now it's working!
Thanks for the guidance,
-Charlotte
