R help - Apr 2016 - Could not find function "pointsToRaster"

Dear All,
I have a script that draws longitude and latitude of lightning
occurrence. This script was running fine before. But when I changed my
system and do a fresh install on another laptop, this error persist.
 source("script")
Error in eval(expr, envir, enclos) :
  could not find function "pointsToRaster"

I have tried to see if  there is any other package I need to install
to take of the problem, I could not see. Already, when I installed
raster, it installed its dependencies such as sp.
Can any body please bail me out.

Thanks
Ogbos

Dear Ogbos Okike,

I can't know how your script depends on pointsToRaster(), but googling
around I found that the function seems to have been marked as obsolete:

Hope that helps,

Hi,

A terrific resource for this type of issue (and pretty much anything related to
R) is http://rseek.org/  I'm sure I use it at least daily.  Check out ...

http://rseek.org/?q=pointsToRaster

The first hit is about pointsToRaster() - it has been replaced by
raster::rasterize()

Cheers,
Ben

Dear All,
Thanks for your inputs. I did replace pointsToRaster () with
raster::rasterize(). Below is part of my script.

But I got another error:
Error in (function (classes, fdef, mtable)  :
  unable to find an inherited method for function ?rasterize? for
signature ?"RasterLayer", "matrix"?

Thank you for more inputs.

 colnames(k)<-c("y","x")

pr<-raster::rasterize(r,xy)

#pr<-pointsToRaster(r,xy)
