[R] vectorization of rolling function

Hello I use R to run a simple model of rainfall interception by vegetation: rainfall falls on vegetation, some is retained by the vegetation (part of which can evaporate), the rest falls on the ground (quite crude but very similar to those used in SWAT or MikeSHE, for the hydrologists among you). I

[R] Plotting multivariate time-series with ggplot2

Hello all. Let's say I have a multivariate time-series, obtained from 2 loggers returning a numeric value and a factor giving additional information about this numeric value, for instance its accuracy: data<-data.frame(date=rep(seq(from=as.Date("2012-01-01"), by=1, length.out=100), 2), logger=c(re

[R] overlaying zoo plots in lattice

Hello Let's say I have a multivariate zoo timeseries (synchronised automatic loggers at different places): library(zoo) library(lattice) library(latticeExtra) x<-zoo(data.frame(a=rnorm(100), c=rnorm(100), b=rnorm(100)), seq(from=as.Date("2010-01-01"), by="day", length.out=100)) and a dataframe
