Hi, I guess the backslash should not be used as the separator for strsplit() in compareVersion(), because the period in [.] is no longer a metacharacter (no need to "escape" it using a backslash): https://github.com/wch/r-source/blob/trunk/src/library/utils/R/packages.R#L866-L867 > compareVersion function (a, b) { .... a <- as.integer(strsplit(a, "[\\.-]")[[1L]...

...ule version require version use version constructs which is kind of what I am looking for (especially 'use' which is evaluated at compile time), but R seems to have lost the version= argument to require(). The best I have been able to come up with are constructs of the form if ( utils::compareVersion(utils::packageDescription("data.table", fields="Version"), "1.5") < 0 ) stop("Need data.table version 1.5 or later") if ( utils::compareVersion(as.character(getRversion()), "2.11") >= 0 ) stop("Does not work yet with latest R.") B...

...N packages, many boilerplate code from a single author and most use the version as a printable character string. A few are clearly wrong: E.g. if(getNamespaceVersion("reticulate") >= "1.36.0") will be false it that package ever reaches "1.100.0".

When loading a package with library(APkg) or require(APkg) I would like to make sure that (1) the correct version of [R] is installed. If not an informative error message should be given. I would also like to make sure that (2) another required package which is loaded from within the APkg package (by require(OtherPkg)) is of a certain version or later. First of all, I believe that the check

Hello, I often find myself writing code like : if( require( "foo" ) && compareVersion( packageDescription( "foo")[["Version"]], "2.1" ) < 0 ){ # code that uses version 2.1 of foo } else { stop( "could not load version >= 2.1 of foo" ) } Would it make sense to include something like this in require, library, etc ... require( &quo...

I mean the `numeric_version` object not a numeric (double/int). Basically to protect me from myself I'd prefer not to have to remember to wrap `getNamespaceVersion()` with `as.package_version()`. I suspect a grep of CRAN may highlight others who are erroneously comparing character objects rather than a comparison between a `numeric_version` object and a character. Tim On 17/10/2024
