[R] create a gui with a button to change graphic?

[bogdan romocea]

Adapt the function below to suit your needs. If you really want to
plot 5 minutes at a time, round the time series to the last MM:00
times (where MM is in 5*0:11) and have idx below loop over them.

splitplot <- function(x,points)
{
boundaries <- c(1,points*1:floor(length(x)/points),length(x))
for (i in 2:length(boundaries)) {
    idx <- boundaries[i-1]:boundaries[i]
    plot(idx,x[idx],type="o")    #here you may prefer time.of.x[idx] to idx
    }
}
#examples
par(ask=TRUE) ; splitplot(rnorm(1000),350)
par(mfrow=c(3,1),ask=FALSE) ; splitplot(rnorm(1000),350)
