Interleaves the rows of two GAUSS dataset files that have been sorted on a common variable to produce a single file sorted on that variable.
intrleav(infile1, infile2, outfile, keyvar, keytyp)¶
infile1 (string) – name of input file 1.
infile2 (string) – name of input file 2.
outfile (string) – name of output file.
keyvar (string) – name of key variable; this is the column the files are sorted on.
keytyp (scalar) –
data type of key variable.
numeric key, ascending order
character key, ascending order
numeric key, descending order
character key, descending order
// Varnames varnames = "id"$|"x"$|"y"; // Create first data file id1 = seqa(1, 1, 100); x1 = rndn(100, 1); y1 = rndn(100, 1); saved(id1~x1~y1, "mydata_1.dat", varnames); // Create second data file id2 = seqa(101, 1, 100); x2 = rndn(100, 1); y2 = rndn(100, 1); saved(id2~x2~y2, "mydata_2.dat", varnames); // Interleave both files into one // Define infiles infile1 = "mydata_1.dat"; infile2 = "mydata_2.dat"; // Define key variable for merging keyvar = "id"; /* ** Define key variable type ** 1 Numeric, ascending order ** 2 Character, ascending order ** 3 Numeric, descending order ** 4 Character, descending order */ keytyp = 1; // Define outfile name outfile = "mydata_total.dat"; /* ** Combine both infiles using ** intrleave to form one outfile */ intrleav(infile1, infile2, outfile, keyvar, keytyp);
The two files MUST have exactly the same variables; that is, the same number of columns AND the same variable names. They must both already be sorted on the key column. This procedure will combine them into one large file, sorted by the key variable.
If the inputs are null (
"" or 0), the procedure will ask for them.
