[TRNSYS-users] R: Create a new type

[jeannieboef]

The function getsimulationtimestep must be defined in your  
trnsysfunctions.f90 module which I assume you also recompiled. MP  
maybe module parameter? I've never seen this error whist compiling,  
but "undefined reference" usually refers to a function name or  
whatever name that was not defined in your type or in the modules  
included in your type.
