pik-piam / gdx Goto Github PK

How about changing the default of parameter react in readGDX() from warning to silent?

Little code-census: searching through calls to readGDX() in all pik-piam packages:

Most users don't seem to care too much whether objects are found or not, and of those who seem to care, most are actually ok with silent, and some don't care enough to put down a legal parameter.

Of the first group (not caring or ok with silent), 544 calls are in the remind package, which elicits a truck load of warnings about

<some_parameter> not found in GDX! <some_parameter2> returned

due to all the renaming that has been going on.

This makes warnings quite meaningless, because a) this is designed-for behaviour and b) it also makes it impossible to see any other warnings, since R only keeps 50 of them.

So how about changing the default to silent, cutting down on all those warnings?

Using this file /p/projects/rd3mod/gdx_file_breaking_readGDX.gdx,

this works:

str(readGDX('gdx_file_breaking_readGDX.gdx', 'v37_emiIndCCSmax', field = 'l'))

Formal class 'magpie' [package "magclass"] with 1 slot
  ..@ .Data: num [1:12, 1:40, 1:5] 0 0 0 0 0 0 0 0 0 0 ...
  .. ..- attr(*, "dimnames")=List of 3
  .. .. ..$ all_regi: chr [1:12] "CAZ" "CHA" "EUR" "IND" ...
  .. .. ..$ ttot    : chr [1:40] "y1900" "y1905" "y1910" "y1915" ...
  .. .. ..$ emiInd37: chr [1:5] "co2cement_process" "co2cement" "co2chemicals" "co2steel" ...

but this doesn't:

readGDX('gdx_file_breaking_readGDX.gdx', 'v37_emiIndCCSmax', field = 'l', 
         format = 'first_found')

NULL
Warning message:
In readGDX("gdx_file_breaking_readGDX.gdx", "v37_emiIndCCSmax",  :
  No element of v37_emiIndCCSmax found in GDX! NULL returned

Using the current REMIND input.gdx works, though. Really weird interaction of .gdx file and readGDX() code.
