FCS Express can integrate R scripts via the new R integration tools in the Tools tab→Transformations→Transformations button which will launch the Transformations navigator. Please refer to www.r-project.org to learn more about R. The goal of R integration and implementation in FCS Express is to allow users to run their own R scripts and work on the resulting output directly within FCS Express as new parameters and cluster transformations. If you have any questions about R integration with FCS Express after reading the topic information below do not hesitate to contact support@denovosoftware.com.  

 

Note: On the PC version of FCS Express, R and any R packages required to run R scripts, need to be installed in order to take advantage of the R integration tools (see below how FCS Express 7 finds R executables). The MAC version of FCS Express does not require R to be installed on the machine. However, any R package required to run the user's R script, needs to be installed in order to take advantage of the R integration tools. Please refer the Installing R packages on the MAC version of FCS Express chapter to learn more on how to install R packages on the MAC version of FCS Express.

 

How FCS Express 7 finds the R executables on a PC

1. Look for the R_HOME environment variable. If this is set, then FCS Express will use this value for as the install path for R.

1. If not, then FCS Express 7 we will look in the system registry for the main installation path for R. (Found at HKEY_LOCAL_MACHINE\SOFTWARE\R-Core\R\InstallPath or HKEY_CURRENT_USER\SOFTWARE\R-Core\R\InstallPath). Note that this is normally set by the R installer, and the user will not need to set that up manually.

2. If the main registry key is not set, then FCS Express 7 will look in the (HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER)\SOFTWARE\R-Core\R folder. Then, FCS Express 7 will find the latest installation of R in the folder and use the InstallPath key from this installation.

 

If you have multiple version of R installed on your PC and you want to point FCS Express 7 to one of them, you need to specify this in the R_HOME environment variable.
