RStudio 1.2 does not support 32-bit R #16
Description
June 2019: Unable to run 32-bit R from RStudio version 1.2.1335 (preventing use of RODBC package to query Access databases)
See this forum post for details: https://community.rstudio.com/t/unable-to-select-32-bit-r-version-in-rstudio-v1-2-1047-1-preview/16404/32
Developer indicates 32-bit R will be supported in later updates to RStudio v1.2 (comment May 8, 2019), but as of June 25, 2019 this has not been implemented yet.
Interim solution: re-install and run RStudio version 1.1.463 until the patch for version 1.2 is implemented.
