Assigning large matrices #2

Open harrigan opened 13 years ago

harrigan commented 13 years ago

I am having trouble assigning large matrices.

require 'rinruby'
R.m = Matrix.zero 5

produces

...
rm(.RINRUBY.PARSE.STRING)
d=matrix(c(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0), 5, 5, TRUE)
print('RINRUBY.EVAL.FLAG')
...

which is fine but

require 'rinruby'
R.m = Matrix.zero 50

produces

...
rm(.RINRUBY.PARSE.STRING)
d=matrix(c(0,0,0,0,0 [snip] 0,0,0,0,0), 50, 50, TRUE)
print('RINRUBY.EVAL.FLAG')
Error: unexpected symbol in ",0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0"
...

when using RinRuby 2.0.1, R 2.11.1, and Ruby 1.9.1p376 on Mac OS X 10.6.5.

Bug confirmed. Working on it. Try using rserve-client...

harrigan commented 13 years ago

Thank you, no problem with rserve-client.

clbustos commented 13 years ago

Cool! Anyway, I will fix the bug.

klaffenboeck commented 9 years ago

Was this bug ever fixed? Problem still seems to exist with matrices bigger than (approximately) 200 entries

clbustos commented 9 years ago

The problem is tricky, because is related to the way R creates sockets and ruby interacts with it. I focus my efforts on rserve-client, because allows a more faster and secure way to manage R.

This issue may be solved with #30 , and can be closed.
