[R] : Question about correlation between data.
hi everybody, I'm a student, and I'm new using R! I'm looking for statistical help hoping somebody can answer me! This is my problem: I have 2 temporal series. The firstone is a series of mesured data (height of monitorated points), the second is a series of temperature (in Celsius degree). Using Matlab I have built the two graphs (Measured Data - Time & Temperature - Time). Looking those graphs I can surely say that there is a clear correlation beetween theme, and also that the measured data are surely influenced by the variations of temperature. Unfortunately my statistical knowledges are not that large so using R seems quite difficult to me. My question is: is there a code already written the can compare the 2 temporal series and can find the correlation between the data??? And also: is there a code that can correct the Measured Data from the influence of temperature and return a clean data??? if you want I can send you the .txt file with data. Thanks Antonio Gonelli - University of Ferrara - Italy
