Hello,
The following script fails on gretl cvs build date 2015-01-07 running on Win 7 64 bit
while the example code in help works fine.
set echo off
nulldata 50
series x = normal()
series y = normal()
list list1 = null
string SeriesName
loop i = 1.. 10
SeriesName = sprintf("test%d",i)
list1 += genseries(SeriesName, x * y)
endloop
list list1 print
it yields the following error
gretl version 1.10.0cvs
Current session: 2015-01-07 14:20
periodicity: 1, maxobs: 50
observations range: 1 to 50
Generated series x (ID 2)
Generated series y (ID 3)
Generated list list1
Data types not conformable for operation
> list1 += genseries(sprintf("test%d",i), x * y)
Also, I cannot figure out how to reliably replicate this. But sometimes gretl terminates
unexpectedly on the second time a script is run when something (I am not sure what) is
wrong with a genseries() call. Sorry I cannot yet give more info on this, but I will keep
experimenting.
Thanks,
Logan
8:50 p.m.
I get a different error in the console: "The symbol 'x*y' is undefined"
(same system & build date)

Sorry. I get that error, too, when there are no spaces between "x*y"
Could you try " x * y" ?

Yep - now I get the same error as you.

Oof, this is quite a subtle one. The problem is that '*' is given a
special interpretation when defining a list (wildcard). I'll have to
think about the best fix, but in the meantime you can make this work
by quoting the "genr" expression:
list1 += genseries(sprintf("test%d",i), "x * y")

This idiom will now work OK. (It's no longer necessary to quote the
expression "x * y", the workaround I mentioned yesterday.)
Also, I cannot figure out how to reliably replicate this. But
sometimes gretl terminates unexpectedly on the second time a script
is run when something (I am not sure what) is wrong with a
genseries() call.
In looking into this I found a possible cause of flakiness in
genseries(), which should also be fixed now (CVS and snapshots).

Thanks. I will update my gretl install and try to crash it. ;-)
Quick question, is a string ok for the second argument? The help indicates a comand line
(RHS of the assignment statement) without quotes. I have been putting a string variable in
and it works. But is this an abuse of the function on my part?

Be my quest!

It's a fairly new function, and originally it required a string
representation of the relevant formula as the second argument. I
recently rejigged it to accept the series-defining expression
straight, for reasons of efficiency. However, for backward
compatibility the string second argument is still accepted.
(Efficiency: in the string case we have to "loop back" and call a
second instance of "genr" to create the target series, but with the
straight formula the target series gets generated on the fly, in the
same way as any compound series argument to a function.)
