...on. When I select plot = TRUE in the ccf() I get a graph which has ACF on the y-axis, which would suggest that these y-values are the auto-correlation values. How should I adjust the code to produce a plot that provides the cross-correlation values? Here is my code: w002dat <- read.csv("w054_1128958_08NM174.csv", header=TRUE) w002dat$date <- as.Date(w002dat$date,"%m/%d/%Y") attach(w002dat) w002ccfhdgw <- ccf((gwneg), (hydro), lag.max = 400, type = c("correlation"), plot = TRUE, na.action = na.exclude) Thank you Arelia [[alternative HTML version deleted]]
