Thank you for the advice! I checked validity of the packages and reinstalled "too new" once appearing in the warning. However, I could not install a correct BiocParallel version using
if (!requireNamespace("BiocManager", quietly = TRUE)) install.packages("BiocManager") BiocManager::install("BiocParallel", version = "3.9") I obtain BiocParallel 1.17.3 not 1.17.1, and calling BiocManager::valid() I get the following returned: > BiocManager::valid() > * sessionInfo() > R Under development (unstable) (2018-11-30 r75722) > Platform: x86_64-apple-darwin15.6.0 (64-bit) > Running under: macOS Mojave 10.14.1 > Matrix products: default > BLAS: > /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib > LAPACK: > /Library/Frameworks/R.framework/Versions/3.6/Resources/lib/libRlapack.dylib > locale: > [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8 > attached base packages: > [1] stats graphics grDevices utils datasets methods base > loaded via a namespace (and not attached): > [1] BiocManager_1.30.4 compiler_3.6.0 tools_3.6.0 yaml_2.2.0 > > Bioconductor version '3.9' > * 0 packages out-of-date > * 1 packages too new > create a valid installation with > BiocManager::install("BiocParallel", update = TRUE, ask = FALSE) > more details: BiocManager::valid()$too_new, > BiocManager::valid()$out_of_date > Warning message: > 0 packages out-of-date; 1 packages too new Starting a fresh session and loading SummarizedExperiment I still obtain the warning: Warning message: > multiple methods tables found for ‘lengths’ and the sessionInfo() gives: R Under development (unstable) (2018-11-30 r75722) > Platform: x86_64-apple-darwin15.6.0 (64-bit) > Running under: macOS Mojave 10.14.1 > Matrix products: default > BLAS: > /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib > LAPACK: > /Library/Frameworks/R.framework/Versions/3.6/Resources/lib/libRlapack.dylib > locale: > [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8 > attached base packages: > [1] parallel stats4 stats graphics grDevices utils datasets > [8] methods base > other attached packages: > [1] SummarizedExperiment_1.13.0 DelayedArray_0.9.0 > [3] BiocParallel_1.17.3 matrixStats_0.54.0 > [5] Biobase_2.43.0 GenomicRanges_1.35.1 > [7] GenomeInfoDb_1.19.1 IRanges_2.17.1 > [9] S4Vectors_0.21.6 BiocGenerics_0.29.1 > loaded via a namespace (and not attached): > [1] lattice_0.20-38 bitops_1.0-6 grid_3.6.0 > [4] zlibbioc_1.29.0 XVector_0.23.0 Matrix_1.2-15 > [7] tools_3.6.0 RCurl_1.95-4.11 yaml_2.2.0 > [10] compiler_3.6.0 GenomeInfoDbData_1.2.0 Let me know if you see a potential fix.
