Post onexperiment building: how can i read randomly from a string-matrix ?

Hi there,

I posted a message yesterday being stuck on building my experiment,
but most of those problems are solved now. Only problem now is how i
can read randomly from a string matrix. I want to present randomly
either the letter 'R' or 'L'. My idea was to create a matrix with
those two strings in it and then randomly selecting one entry from
that matrix e.g.:

text={'R';'L';];
rand(text,1);

is this legitimate code? i guess not; it doesn't seem to work at
least.

so if anyone has any suggestions on this... please react

greetings
Jeroen
