#3688: impossible to start grass from Rstudio in Windows

     Type:  defect      |     Status:  new
 Priority:  normal      |  Milestone:  7.4.3
Component:  Default     |    Version:  7.4.2
 Keywords:              |        CPU:  Unspecified
 Platform:  MSWindows   |
------------------------+-------------------------
 Currently it is impossible to start GRASS from R in Windows (I tested with
 GRASS installed from OSGeo4W). It worked perfectly a month ago or so when
 Roger Bivand fixed some issues. Apparently it is due to an incompatibility
 in dependencies after GRASS was compiled against new GDAL and PROJ.

 Here's the R command (paths must be adapted):

 {{{
 initGRASS(gisBase = "C:/OSGeo4W64/apps/grass/grass-7.4.2RC2",
           gisDbase = "C:/Users/RETA/Documents/grassdata",
           location = "nc_spm_08_grass7",
           mapset = "user1",
           SG = "elevation")
 }}}

 The pop-up error is a missing iconv.dll. All locales were in Spanish as
 well as the laptop I tested on. After many attempts to try to close the
 pop-up error, we got the following in the Rstudio console:

 {{{

 }}}
