Hi, I am experiencing a warning message when I load a large R object created in an R 3.6 session in R 3.5.* , as follows:
``` Warning message: In load(“GDSCv2.RData”) : cannot unserialize ALTVEC object of class ‘wrap_logical’ from package ‘base’; returning length zero vector ``` Of relevant information may be that the large R object (a data structure defined in my Bioconductor package PharmacoGx), was in part created including data frames which were cast from data.tables. I noticed that the ALTVEC class had caused some errors previously in the data.table package. I have two questions: 1. Should I be concerned about this warning? I cannot seem to find what effect it has on the data loaded. 2. Could you point me towards narrowing down the cause of this issue? Ideally, everyone would upgrade R promptly, but even our own institute's HPC cluster is still on 3.5, and the warning does not inspire confidence for some of the less technical members of our group who are using the datasets. -- Petr Smirnov PhD Candidate, Benjamin Haibe-Kains Lab Princess Margaret Cancer Centre University of Toronto psmirnov2...@gmail.com ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
