Does anyone have experience using CRImage? I'm trying to analyze some H&E images, but am having some installing one of it's packages. I can get the majority of the functions of CRImage to work, including segmentImage and createClassifier, but for some reason I cannot get 'createTrainingSet' to install. Here is the error I receive:

> biocLite(c("createTrainingSet"))
BioC_mirror: https://bioconductor.org
Using Bioconductor 3.7 (BiocInstaller 1.30.0), R 3.5.1 (2018-07-02).
Installing package(s) ‘createTrainingSet’
Warning message:
package ‘createTrainingSet’ is not available (for R version 3.5.1) 

Does this have to do with the version of R that I am running? Any advice would be extremely helpful! Thanks!

Update: I figured it out! :) It's working great! CRImage is great!
