Is there any funktion like colMeans to get the maximum of the day e.g. colMax?
period.apply(df.xts, endpoints(df.xts, "days", 1), colMeans)
Or are there any other solutions? Thanks

1No, but you could use `function(x) apply(x,2,max)`. – Joshua Ulrich Feb 17 '14 at 15:50

Thx! There is one in `matrixStats` but not working with xts;-) – Herr Student Feb 17 '14 at 16:11
