envar 0.1.1

  • New metadata() function. Added at the end of a pipeline, it writes a provenance summary of the whole download: the source URLs and the date each file was downloaded, the variables produced, the temporal period they refer to, the native resolution of every source dataset, the resolution, CRS and extent of the output, and the processing settings used (those of par_set() and the arguments of every dataset function called). The summary is written as a readable report (envar_metadata.txt) and as a table (envar_metadata.csv) and is also returned with the pipeline object. As in corr_check(), an interactive session asks at the console where to store the files, so a pipeline containing both functions asks once for each of them.

  • The correlation plot written by corr_check() is no longer a fixed 2000 x 2000 pixel image: its side now grows with the number of variables, from 1200 up to 2000 pixels at 300 dpi, so that small sets of variables are not drawn on a mostly empty sheet.

  • par_set() no longer writes to the user’s home filespace without permission. The cache argument now defaults to NULL, which asks once per interactive session whether the persistent download cache (in tools::R_user_dir()) may be used, and always answers “no” in non-interactive sessions, where a session temporary directory is used instead. Pass cache = TRUE/FALSE, or set options(envar.cache = ), to skip the question.

  • chelsa() now fails with an informative message when vars = "bio" (which asks in the console which bioclimatic variables to download) is used in a non-interactive session, instead of failing later with an unrelated error. The corresponding example has been removed from the documentation.

  • roads() gains the two aggregated variables "primary" (sum of road classes 4 and 5) and "other" (sum of road classes 1, 2 and 3), alongside the existing "all" and the five single classes. Because "primary" now names the aggregated group, the single class 2 is requested with "class2" or "primary class". The download links of the aggregated layers were updated.

  • The roads() documentation and the “Available variables” article now describe how the road classes are derived from OpenStreetMap and what the aggregated layers contain.

  • The land mask example in the “Package overview” article now uses a CHELSA climatology, which provides values over the sea, so that the effect of land = TRUE is actually visible.
