I got the following error using ChemmineR function propOB() to obtain molecular decrsiptors from an sdf file. This is the code as in the manual example and for some reason it keeps throwing this error.
> library(ChemmineR) > data(sdfsample) # Call propOB() > propOB(sdfsample) Error in getClass(Class, where = topenv(parent.frame())) : “_p_std__string” is not a defined class
This function is very similar to the one from package ChemmineOB, and get the same error using the example
> library(ChemmineOB) > molRefs = forEachMol("SMILES","C1CCCCC1\ttest-compound-name",identity) > prop_OB(molRefs) Error in getClass(Class, where = topenv(parent.frame())) : “_p_std__string” is not a defined class
R version 4.0.3 (2020-10-10)
Anyone encountered and solved this problem? Thanks
