Hi there,
I have encountered two kinds of strange bugs with gretl 2015-10-16 x86_64 on Windows:
1.) Opening a file like the attached one with a "just launched" gretl instance
will result in automatically substituting the string variables with IDs. However, starting
gretl with a script which opens the file with the --preserve option works fine. And, after
this was done first within the current gretl instance, if one "selects" open
from the menu, it works also as-if the "preserve" option is turned on. Cost me a
bit of time to get to it...
2.) The same file as attached, opened such that the string variables "name" from
t1 to t3 are there. Then restrict the sample such that "t2" is not included. The
factorized boxplot will have as x-tics t1 , t2. The same is true if you take the
"--permanent" option. This made me more of a headache until I got there ;)
I read that there are some bugs in the recent non-release gretl version but I do not know
if this was already known.
The example file and the example scripts are attached.
PS: Is there an easy way to pipe individual varnames for the x-tics in a boxplot to
gnuplot via the {} command? And, why can I do something like "Values = (Values ==1 ?
10 : Values)" but not "Name = (Name == 't1' ? 'uiui' :
Name)"? Is there an alternative to do so which I am not aware of?
Regards and many thanks
Frederik

Please try the current gretl snapshot. Some improvements have been
made since 2015 in the handling of string-valued series in the GUI.
The --preserve option should be irrelevant here, since if I
understand your experiment, there are no predefined objects to be
preserved or discarded in this case.
That said, your example.csv doesn't contain enough data for gretl to
be able to produce sensible boxplots. If I double up the data (add a
second copy of the values below the original) then I can see some
plots.

There's a rule in gretl (perhaps not always apt) that you cannot
assign new values to an entire string-valued series. However, you
can do something similar in a loop:
loop i=1..$nobs --quiet
if Name[i] == "t1"
Name[i] = "uiui"
endif
endloop
(Note that 'string' with single quotes is not allowable syntax in
gretl.)

Hello,
with the current snap-shot the problems do not occur at all. Thanks a lot and thanks for
the loop example, too!
