Solved, now working example!
I have a set of time series that is populated in a folder structure as follows:
TimeSeriesData\Config_000000\seed_001\Aggregate_Quantity.txt
…
TimeSeriesData\Config_000058\seed_010\Aggregate_Quantity.txt
And in each file there is a first line containing a character, followed by lines containing the data. E.g.
share
-21.75
-20.75
…
Now, I would like to import all those files (at best, without specifying ex post the number of configs and seeds, at worst with supplying it) into single time series of the like: “AggQuant_config_seed” where config relates to the config ID and seed to the seed id.
I tried the following (using the non-preferred way), but “parsing” the “path” does not work / I do not know how to do it.
string base = "TimeSeriesData/Config_"
string middle = "/seed_"
string endd = "/Aggregate_Quantity.txt"
string path = ""
loop for (i=0;i<=58;i+=1)
loop for (j=1;j<=10;j+=1)
path = ""
sprintf path "%s%06d%s%03d%s",base,i,middle,j,endd
append @path #will be named share
rename share Agg_Q_$i_$j #rename
endloop
endloop
To sum up the problem, the following does not work:
string path="somwhere/a_file.txt" #string holding path
#wrong: append $path #use append on string
append @path #works!
And if possible, a way to search recursively through a set of folders, using the folder information together with file-information for the variable name, would be nice. Is that possible within gretl?
I realize that in many cases I would like to refer to a specific “help” section like those for functions and commands, but for operators instead (like “$”, which is obviously wrong here).
