[BioC] combining data from two R arrays

[Richard Harrison]

Deal all,

I have two identically sized arrays, one logical and one numerical. I  
would like to take the TRUE/FALSE data from the logical array and set  
every false prediction to 0 in the numerical array. I tried:

     yn[throwOut,]=NA - where throwOut is the logical array and yn is  
the numerical one. I got the following error:

Error in yn[throwOut, ] = NA : incorrect number of subscripts on matrix

Any ideas?


Thanks
Richard Harrison
