The following SAS code is probably reading two excel files. What else is it doing? Could you please give a high-level overview of the code from R's perspective?
# Part A
LIBNAME RA 'C:\Users\Steve\UNDO\ADRAW';
LIBNAME XX 'C:\Users\Steve\UNDO\PHD';
# Part B
PROC IMPORT OUT=WEEK DATAFILE= "C:\Users\Steve\input\Week.xlsx" DBMS=xlsx REPLACE;run;
PROC IMPORT OUT=TRIP DATAFILE= "C:\Users\Steve\input\Trip.xlsx" DBMS=xlsx REPLACE;run;
# Part C
Data trip;
set trip;
fmtname='TRIP';
Start=Start;
label=TRIP;run;
Proc format CNTLIN=TRIP;run;
# Part D
Data Week;
set Week;
fmtname='WEEK';
Start=Start;
label=Week;run;
Proc format CNTLIN=WEEK;run;
*end ;
