Error in .C() #14

Closed wtf13 closed 6 years ago

wtf13 commented 7 years ago

Hi, I have been encountering the following error persistently on my computer when trying to run the npudensbw function from the np library: Error in .C("np_density_bw", as.double(duno), as.double(dord), as.double(dcon), : "np_density_bw" not available for .C() for package "np".

Could you kindly advise on the problem please? My np package installation has already been updated to the latest and I am running the code on R version 3.4.1.. Would I need any additional installations in order for the code to run smoothly? Thanks in advance for your help!

Greetings,   I will need more information per the FAQ – kindly send code to replicate…

Hi Jeffrey, Thanks for your quick response! Here is the error message when I tried to use the function for the mtcars example dataset.

Appreciate your support and have a great weekend!

Can’t replicate on four different platforms (UNIX, Linux, macOS, windows)… try reinstalling R and the np package perhaps?

Already tried to do so but the same result occurs even after reinstallation~ was wondering if the package has dependencies on other software or the internet? I am trying to run it on a computer that is internet-disabled, not sure if this is the cause of the problem. Thank you so much for helping with this!

JeffreyRacine commented 7 years ago

Nope… are you using binaries or building from source?

I believe it's the binary distribution of R..

JeffreyRacine commented 7 years ago

Something messed up on your system… sounds like a compiler issue… try building from source and see if that resolves…

ok, thanks so much for your advice professor! I would need to have a C compiler installed in my computer to do this then?

JeffreyRacine commented 7 years ago

I presume you are using windows…   https://cran.r-project.org/bin/windows/Rtools/
