Downsampling of RPM traces

Hi,
I have RPM trace signal (respiratory data) sampled at 26 Hz. I want to downsample RPM trace signal to 5.2 Hz. Does anyone know how to downsample this trace signal to 5.2 Hz?
Thanks in advance.

I assume that the signal is sampled regularly, and a fixed sampling interval.
A prototype call to it would be:
RPMrs = resample(RPM, 52, 260);
so the output will be sampled at 5.2/26 of the original rate.
Note that if it is not uniformly sampled, first follow the procedure in Resample a Nonuniformly Sampled Data Set, then do the rate resampling.
