spline_stats function

Computes background quantities using splines

This function computes 4 splines, from median, iqr, mean and standard deviation values.

spline_stats(dat)

Arguments

• dat: The data matrix

Returns

A list with following components - med.spline: The spline computed from the median values.

• iqr.spline: The spline computed from IQR values.

• mean.spline: The spline computed from mean values.

• sd.spline: The spline computed from standard deviation values.

• mean.dat: The mean of the data matrix.

• sd.dat: The standard deviation of the data matrix.

Examples

out <- gen_stream(1, sd=15)
zz <- as.matrix(out$data)
sstats <- spline_stats(zz[1:100,])
oldpar <- par(mfrow=c(2,1))
image(1:ncol(zz), 1:nrow(zz),t(zz), xlab="Location", ylab="Time" )
plot(sstats[[1]], type="l")
par(oldpar)
