Deterministic order of parameters in function call?

[raff-k]

Dear RQGIS-team,

I am just wondering if there is a deterministic order how the function parameter have to be set in the function. - If there is, maybe you could mention that in the description somewhere (and if you already did, I am sorry for my nescience).

Computing...
data(dem)
RQGIS::run_qgis(alg = "saga:gridbuffer", FEATURES = dem, BUFFER = "tmpBuf.sdat", BUFFERTYPE = "1", DIST = "1", load_output = TRUE)
... I got:

Error in pass_args(alg, ..., params = params, qgis_env = qgis_env) :
Invalid argument value 'C:/Users/USER/AppData/Local/Temp/RtmpI9zYec/1' for parameter 'DIST'

But ...
RQGIS::run_qgis(alg = "saga:gridbuffer", FEATURES = dem, DIST = "1", BUFFERTYPE = "1", BUFFER = "tmpBuf.sdat", load_output = TRUE)
... works fine :-)

Interesting, shouldn't be that way... will take care of this tomorrow. Thanks for noting!

Commit 45aef93 should fix your issue. However, it works only with QGIS 2.14. QGIS 2.18 only produces a prj-output file. Well, another QGIS issue, will add it to our list.
