Good day everyone. I have a large dataset of 1 min wind speeds covering 5 years.
How can I make an array of maximum daily values? The vectors I have are: 'VDATE' with dates in format '%Y-%m-%d' (like '1992-10-28') and 'WS' with wind speed data (same number of elements as VDATE). I want an array with 2 columns: Max daily wind speed and corresponding day. Has anyone got an elegant way of doing that? (My background is in C++ I would tend to use loops but that is not very elegant in R, isn't it?) Augusto -------------------------------------------- Augusto Sanabria. MSc, PhD.
