Also if this is a time series you may wish to represent it as such to facilitate other computations as well. This assumes that the DATE column is first and the remaining columns are numeric:
library(zoo) mypath <- "/whatever/myfile.csv" z <- read.zoo(mypath, sep = ",", header = TRUE, format = "%d/%m/%Y") plot(z) See the three zoo vignettes for more info.
