Hi, I am using the clusters function in the evd package and was wondering if anyone knew how to set the row names as date/time objects. My data has 1 column of date and time and another of wave height (H).
My two options are: 1 - When in import the data using read.table make sure that the row.names is set = 1 giving row names to the H data. 2 - Import H from the data file and set the row names using row.names(H) <- x where x is the data/time data. The problem is when I try to use the cluster function on either I get the following error: > Clusters <- clusters(H, 3.0, r=144, plot=TRUE, cmax=TRUE, row.names=TRUE) Error in xy.coords(x, y, xlabel, ylabel, log) : (list) object cannot be coerced to type 'double' In addition: Warning message: In min(diff(xdata)) : no non-missing arguments to min; returning Inf Does anyone know how to set date/time row names in the cluster function?
