Function/file names are hypothetical. Say I have written myfunction.R, which calls myfunction.c via .C("myfunction", ...).I've compiled successfully myfunction.c via R CMD SHLIB myfunction.c in the terminal. Then, in the R console: dyn.load("myfunction.so") source("myfunction.R") test <- myfunction() # works fine So everything is in order, myfunction works perfectly. Now I want to include myfunction() into a package called mypackage. Here's what I did: 1) I've added PACKAGE = "mypackage" in the .C() line in myfunction.R. 2) I put myfunction.R into the R folder of mypackage 3) I put myfunction.c into the src folder of mypackage 4) I created myfunction.Rd into the man folder I then build the package via R CMD build mypackage. All good. However, when I run R CMD check mypackage, I get the following error (note that I translated from french, might be a bit different in english): Error in .C("myfunction", ...): C symbol name "myfunction" cannot be found in the DLL for package "mypackage" I would appreciate some help here. Please do not refer my to "Writing R extensions" - if the answer's in there, I don't understand it.
What do you get from R CMD INSTALL mypackage?
