As it turns out, there was something wrong with the way that the column and
row names were set up when the wind frequency table was made. As I
mentioned, the same data (all the data) was plotted 6 times around the
circle (rose plot). The way I've resolved this is by writing the data to a
.csv file and bringing it back in and skipping the first row (column names):
Wind_table <- read.table("myTable.csv", skip=1, header = FALSE, sep = ",")
then deleting the first column (row names).
Wind_table <- Wind_table[,-1]
Then rename the column and row names and run rosavent.... and it works.
Thanks,
Kevin
