Dear List, I have run into trouble with the execGRASS command copied below and can't figure
out what I'm doing wrong. It runs fine without the size=11 argument (takes the default value
of 3). Can

storage.mode(11)

[1] "double"

is.integer(11)

[1] FALSE

is.integer(11L)

[1] TRUE

Just because it looks like an integer, it doesn't mean it is.

Hi Roger

this has bittan many users, including myself, as it is a little aux contraire to R, as here 11 is
acepted as integer in most circumstances.

Would it be possible to use a different check for integer e.g.

if(as.integer(x) == x) then {x <- as.integer(x)} else {ERROR}

I have the feeling that would be more in line with the treating in R of different numerical
storage modes.

Cheers,

Rainer

Roger

someone please help. Thanks in advance, Ravi

Command: execGRASS("r.neighbors", parameters=list(input=patmap, output=n11map,
method="median", size=11), flags=c("overwrite", "c"))

Error: Error in doGRASS(cmd, flags = flags, ..., parameters = parameters, echoCmd = echoCmd)
: Parameter <size> does not have integer value
