Can anyone please tell me why I am getting this error? library(zoo) Z.index <- as.Date(sample(12450:15500, 3000)) Z.data <- matrix(rnorm(300), ncol = 1)
data1 <- zoo(Z.data, Z.index) fnc = function(data1) { selection2 = select.list(c("Mean"), multiple = F) Mean = function(dataa) mean(dataa) return(aggregate(data1, as.yearqtr, selection2)) } fnc(data1) I got following error : Error in get(as.character(FUN), mode = "function", envir = envir) : variable "Mean" of mode "function" was not found What would be the correct way?
