[R-sig-Geo] Problems with spgrass6 and initGRASS in Fedora 14

[Julian Burgos]

Ok, so I run the initGRASS() and gmeta6() functions line by line to
try to isolate the problem.

First, the following line gives me an error:
> SYS <- get("SYS", envir = .GRASS_CACHE)
Error in get("SYS", envir = .GRASS_CACHE) :
  object '.GRASS_CACHE' not found

I can get the function running f I fix the value of SYS to "unix" and
change all environment references to

envir=spgrass6:::.GRASS_CACHE.

But I get the following error when running the gmeta6() function:

>    gisenv <- execGRASS("g.gisenv", flags = "n", intern = TRUE,
+         ignore.stderr = ignore.stderr)
Command: g.gisenv
Description: Outputs and modifies the user's current GRASS variable settings.
Keywords: general
Parameters:
  name: get, type: string, required: no, multiple: no
  keydesc: VARIABLE, keydesc_count: 1
[GRASS variable to get]
  name: set, type: string, required: no, multiple: no
  keydesc: "VARIABLE=value", keydesc_count: 1
[GRASS variable to set]
  name: store, type: string, required: no, multiple: no
  default: gisrc
[Where GRASS variable is stored]
Flags:
  name: verbose [Verbose module output] {FALSE}
  name: quiet [Quiet module output] {FALSE}
Error in doGRASS(cmd, flags = flags, ..., parameters = parameters,
echoCmd = echoCmd) :
  Invalid flag value: n

I'll keep looking...
