If you are running SciCraft on Windows without a properly installed R you may
get the following error message when executing an R function node: This
feature is unavailable. R is either not installed or not registered in the
registry. Please consult the SciCraft documentation on how to install R
correctly. To fix this problem you need to ensure that R is installed and has
registered its install path in the Windows registry. You have two options for
solving this problem: either reinstall R and during the install, make sure you
enable the option Register R path for use by (D)COM server. The second
option is to create the registry key manually. This is done by placing
the following in a file called e.g. register-r.reg:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\R-core]
[HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R]
"InstallPath"="C:\\Program Files\\R\\rw2001"
"Current Version"="2.0.1"
You can then execute the file. Make sure that you update this text
with the correct path to your R installation.
When something is wrong with an R script you might get the following error
message when you run it inside SciCraft: HCA: Expected results for 2
ports, but plugin returned 0. To see the specific error message give by R you
need to enable R debugging. This is done on the preferences widget, click on
the File menu and then click Preferences. It is recommended to
disable this option when you are not looking for an R error.
