hi everyone! i want to check the autocorrelation function for a univariate time series (streamflow) in a data frame as below:
< DF <- read.table("D:/file path....") < DF year jan feb mar apr ...... dec 1966 0.504 0.406 0.740 0.241 0.429 1967 0.683 0.529 0.780 0.443 0.503 . . . . what i first tried is: acf (DF, plot = TRUE) the resulting plot is correlation between each month ( jan, jan and feb, feb and march....). what i need is a correlation that would help me find out which lag would be the most significant. i know i am missing out something simple here. please bear with me. should i transform my data frame into a vector of series: < DF 01/1966 0.504 02/1966 0.406 03/1966 0.740 .... .... before i do the command acf(DF, plot = TRUE)??? thanks in advance! -- View this message in context: http://www.nabble.com/acf-for-a-univariate-time-series-in-a-data-frame-tp25799751p25799751.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
