I have an array of data.frame(s) that I would like to smooth with loess one at a time. the array is master and the two variable that I am interested in is Period and Quantity. So my first attempt at calling loess is:
loess(Quantity ~ Period, master[[i]]) But I get the following error: Error: NA/NaN/Inf in foreign function call (arg 2) In addition: Warning message: NAs introduced by coercion I did a str on the array element str(master[[j]]): 'data.frame': 58 obs. of 3 variables: Factor w/ 41 levels "10\" Plates",..: 1 1 1 1 1 1 1 1 1 1 ... $ Period : POSIXct, format: "0001-01-20" "0002-01-20" ... $ Quantity: int 0 0 0 0 0 0 0 0 0 0 ... So am I doing something wrong? Thank you.
