monthsAgg(data, process, multiple = NULL, na.rm = FALSE)

Arguments

data	A timeSeries formatted dataset.
process	An aggregation method. See aggregate.

Examples

##Load the data
data(foo)
##Format the data using the timeSeries function.
foo.ts <- timeSeries(foo[,1],"%d/%m/%Y   %H:%M",foo[,3])
##Aggregate the data into 6 month blocks using mins
min.month <- monthsAgg(foo.ts,min,6)
##Aggregate the data into 6 days blocks using max
max.month <- monthsAgg(foo.ts,max,6)
##Aggregate the data into 6 days blocks using max
mean.month <- monthsAgg(foo.ts,mean,6)
#Create a plot of the results
ymin=min(min.month$data);ymax=max(max.month$data)
plot(mean.month,ylim=c(ymin,ymax))
lines(min.month,type="l",lty=3,col="red")
lines(max.month,type="l",lty=3,col="blue")
