Upgrade minimum R version in DESCRIPTION

[amoeba]

Hi pxmake team, while submitting our own package to CRAN today we got a note back about an issue in pxmake that looks like something you'll want to deal with eventually so I'm filing an issue and a PR in case it helps. The reason we got a note is that pxmake is a reverse-dependent of ours.

The issue CRAN notified of us was:

Package: pxmake
Check: DESCRIPTION meta-information
New result: NOTE
    Missing dependency on R >= 4.1.0 because package code uses the pipe
    |> or function shorthand \(...) syntax added in R 4.1.0.
    File(s) using such syntax:
      ‘px_add_totals.px.Rd’ ‘px_aggregallowed.px.Rd’ ‘px_autopen.px.Rd’
      ‘px_axis_version.px.Rd’ ‘px_baseperiod.px.Rd’ ‘px_cellnote.px.Rd’
      ‘px_cellnotex.px.Rd’ ‘px_cfprices.px.Rd’ ‘px_charset.px.Rd’
      ‘px_codepage.px.Rd’ ‘px_confidential.px.Rd’ ‘px_contact.px.Rd’
      ‘px_contents.px.Rd’ ‘px_contvariable.px.Rd’ ‘px_copyright.px.Rd’
      ‘px_creation_date.px.Rd’ ‘px_decimals.px.Rd’ ‘px_description.px.Rd’
      ‘px_descriptiondefault.px.Rd’ ‘px_domain.px.Rd’
      ‘px_elimination.px.Rd’ ‘px_infofile.px.Rd’ ‘px_language.px.Rd’
      ‘px_languages.px.Rd’ ‘px_last_updated.px.Rd’ ‘px_link.px.Rd’
      ‘px_map.px.Rd’ ‘px_matrix.px.Rd’ ‘px_micro.Rd’ ‘px_next_update.px.Rd’
      ‘px_note.px.Rd’ ‘px_notex.px.Rd’ ‘px_order.px.Rd’
      ‘px_precision.px.Rd’ ‘px_showdecimals.px.Rd’ ‘px_source.px.Rd’
      ‘px_stockfa.px.Rd’ ‘px_subject_area.px.Rd’ ‘px_subject_code.px.Rd’
      ‘px_tableid.px.Rd’ ‘px_timeval.px.Rd’ ‘px_title.px.Rd’
      ‘px_units.px.Rd’ ‘px_update_frequency.px.Rd’ ‘px_validate.Rd’
      ‘px_valuenote.px.Rd’ ‘px_valuenotex.px.Rd’ ‘px_values.px.Rd’
      ‘px_variable_label.px.Rd’ ‘px_variable_type.px.Rd’

CRAN very recently added a check for usage of the newer |> and \(...) operators, see https://stat.ethz.ch/pipermail/r-devel/2025-January/083793.html, and my guess is that they'll eventually flag pxmake because your minimum R version is set to >= 3.5.0.

I'll file a PR to update this in case you want to keep using the new operators.

Edit: You can see the NOTE directly on pxmake's check page here: https://www.r-project.org/nosvn/R.check/r-devel-linux-x86_64-debian-gcc/pxmake-00check.html.
