I install the "devtools" package, but when I call it there is no such package

Question

[jabbari.parnian]

Hi all,

I'm trying to install SINCERA package in R, I follow their instructions in github:

install.packages("devtools")
> library(devtools)
Error in library(devtools) : there is no package called ‘devtools’

I have selected all repositories but it doesn't work. Do you know how I can fix this or how I can install the SINCERA package?

Thanks

Hello. What is the output after you run this:

install.packages("devtools")

[jabbari.parnian]

Can you show all output after you type each of the following, please?

install.packages("devtools")

require(devtools)

sessionInfo()

any(grepl('devtools', rownames(installed.packages())))

The devtool is now in my list of packages. Thanks.
