_F_o_r_m_a_t:

     The data frame contains the following columns:

     stacode a numeric vector of the unique station code formed by
     combining the two-digit state number  [state numbers range from 1
     to 48] and the four-digit station number (values range from 0008
     to 9933);                   

     lat, long numeric vectors identifying the lattitudes and
     longitudes of the stations in decimal degree.

     year a numeric vector comprising the year for the records

     month a numeric vector of values 1 to 12, represeting the month
     for the data

     mmtemp a numeric vector of monthly average temperature in
     Fahrenheit scale.

_D_e_t_a_i_l_s:

     The data set was extracted from a large national historical
     climate data, containing data for 48 stations in Texas from 1961
     to 1990. Monthly temperature records as well as the latitude and
     longitude for each station were available.

     Of note, the missing values were coded as -99.99.
