This is about R 4.0.2 (or 4.0.1) help on 'paste'.
End part of the first paragraph in "Details" section: If the arguments are vectors, they are concatenated term-by-term to give a character vector result. Vector arguments are recycled as needed, with zero-length arguments being recycled to '""' only if 'recycle0' is not true _or_ 'collapse' is not 'NULL'. I suggest removing " _or_ 'collapse' is not 'NULL'". 'collapse' has nothing to do with recycling. Description of 'recycle0' in "Arguments" section: 'logical' indicating if zero-length character arguments should lead to the zero-length 'character(0)' after the 'sep'-phase (which turns into '""' in the 'collapse'-phase, i.e., when 'collapse' is not 'NULL') I suggest the explanation to include the term "recycle" or "recycling" like the argument name. For example, 'logical' indicating if "zero-length recycling rule" is in effect, where mix of zero-length and nonzero-length arguments leads to zero-length ... or ... where, in mix of zero-length and nonzero-length arguments, zero-length wins and the nonzero-length arguments are truncated to zero-length ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
