}
data.trash<-ddply(data, .(FileNo, ChannelNo), transform, filtered=applyfilter(ChannelB))
The result from this is
Error in attributes(output[[var]]) <- attributes(value) : invalid time series parameters specified

sFilter: [&...

colSums in C

for(j=0; j<dx[1]; j++) for(i=0; i<dx[0]; i++) z[j] += x[i + dx[0]*j];
}
