Any help appreciated!

Further reading on the internet suggested that this can be devtools issue with function install_github().
However other packages are installing just fine.

Hi,

Thanks for contacting. I think this is an issue in R rather than in devtools. Maybe you can install it locally.

• According to the "DESCRIPTION" file of scNPF, installing all dependencies.

Depends: R (>= 3.1.0), igraph, WGCNA, foreach, doParallel, Matrix, plyr, methods
Suggests: gplots, RColorBrewer
Such as 
>BiocManager::install(c("impute","preprocessCore","GO.db"))

• Download Zip

• Unzip this file and rename this file.

>unzip scNPF-master.zip
>mv scNPF-master   scNPF
>zip -r scNPF.zip scNPF

• Install it locally

>install.packages("C:/Users/yec/Downloads/scNPF/scNPF.zip", repos = NULL, type = "win.binary")
>library(scNPF)
#loading example data
> load(system.file("data","yan.Rdata",package = "scNPF"))
> exp.data <- yan$data
> dim(exp.data)
[1] 17916    90
>##Using String network to smooth expression values.
>load(system.file("data","string.Rdata",package = "scNPF"))
>string.data <- scNPF.pro(x=exp.data, network=string,nThreads=8)

Thanks for your contacting. I have fixed the problem and updated the scNPF package，you can try to install it again

install.packages("devtools")
library(devtools)
install_github("BMILAB/scNPF")
library(scNPF)

if you use the R version 3.6， you may encounter the following problems

install_github("BMILAB/scNPF")
* installing *source* package ‘scNPF’ ... 
** using staged installation 
** R 
** data 
*** moving datasets to lazyload DB 
** byte-compile and prepare package for lazy loading 
Error: (converted from warning) package ‘foreach’ was built under R version 3.6.2 
Execution halted
ERROR: lazy loading failed for package ‘scNPF’ * removing ‘/Library/Frameworks/R.framework/Versions/3.6/Resources/library/scNPF’ 
Error: Failed to install 'scNPF' from GitHub:   (converted from warning) installation of package ‘/var/folders/sc/7

You can set Sys.setenv(R_REMOTES_NO_ERRORS_FROM_WARNINGS=TRUE) to fix it

install.packages("devtools")
library(devtools)
Sys.setenv(R_REMOTES_NO_ERRORS_FROM_WARNINGS=TRUE) 
install_github("BMILAB/scNPF")
library(scNPF)
