شرح پروژه

سلام
من چنتا سوال مربوط به R دارم
ممنون میشم بفرمایید که هزینه و زمان انجامشون چقد طول میکشه

چنتا تمرین کلاسی هستن

Download the sample data from the course website sample_observed_mean_temperature_precipitation_data.csv & sample_model_mean_temperature_precipitation_data.txt                   
Open the time series files in a notebook. Explore annual data and select the columns with variables precipitation (Prec) and temperature (Temp). Save the variables for both model and observation.
Plot the observed temperature and precipitation using the plot function (Temp vs time & Prec vs time).
Calculate, compare and discuss the correlation between
Model precipitation and observed precipitation
Model temperature and observed precipitation
Model temperature and observed temperature
PART B

Download the sample data from the course website sample_daily_data_pr_tmax_tmin_data.txt             
Open the time series file in a notebook. Explore data and select the columns for three variables i.e. precipitation, maximum temperature and minimum temperature.
Plot the daily maximum temperature using the plot function (TMAX vs time) for the first three years (1950, 1951 and 1952). Repeat the same for minimum temperature.
Use your own functions to calculate the variance and standard deviation of maximum temperature for two time periods a) from 1950 to 1960 and (b) 1995 to 2006. Compare the results from the different time periods and conclude your analysis.
Compute the histogram of maximum temperature for two time periods a) from 1950 to 1960 and (b) 1995 to 2006. Compare the results from the different time periods and discuss the maximum temperature extremes events.
