Where can i find the old version about delayedarray

[lshep]

If you do BiocManager::install('DelayedArray') it should automatically download the appropriate version for your R and Bioconductor. It looks like for R 3.6.1 the Bioconductor version appropriate is 3.10 and DelayedArray version 0.12.3 per the landing page. To get a version of DelayedArray >=0.15.14 you will need to be using at least Bioconductor 3.12 which carries DelayedArray 0.16.3 but you need at least R 4.0 to use that version. It is not recommended but you could download the archive from the Delayed Array Landing Page and install it manually but this could result in mixed versions of packages and not properly working DelayedArray as the necessary dependencies may not be available and there were a lot of updates in base R between R 3.6 and R >= 4.0
