Description Usage Arguments Details Value Author(s) See Also Examples

An internal function of erpR to convert milliseconds in points.

1	msectopoints(a, lengthsegment, startmsec, endmsec)

`a`	a number indicating the ms to be converted in points
`lengthsegment`	the length (in points) of the segment
`startmsec`	the time (in ms) of the start of the segment
`endmsec`	the time (in ms) of the end of the segment

This is mostly an internal function of erpR.

The function returns a single value that is the conversion of a from msec to points.

# convert 400 ms to points in a segment of 500 points starting from -200 ms 
# and ending at 1500 (500 Hz).
