Subject | st: reshape value label bug? |
Date | Tue, 11 Jan 2011 10:47:45 -0500 |
I cannot reproduce this with any system or web datasets, but it happens everytime for me; in the below I load a dataset, show that there is no value label named -class2-, apply -reshape-, and suddenly a new value label exists, and is assigned to my new variable _j. This occurs whether or not I specify the variable with option -j()-. What gives? . u analytic, clear . d, short Contains data from analytic.dta obs: 1,653 vars: 12 11 Jan 2011 09:29 size: 46,284 (99.9% of memory free) Sorted by: pat_id . label list class2 value label class2 not found r(111); . reshape long payor_, i(pat_id) (note: j = 1 2 3 4 5 6 7 8 9) Data wide -> long ----------------------------------------------------------------------------- Number of obs. 1653 -> 14877 Number of variables 12 -> 5 j variable (9 values) -> _j xij variables: payor_1 payor_2 ... payor_9 -> payor_ ----------------------------------------------------------------------------- . label list class2 //???????????? class2: 1 ACE-inhibitor or ARB 2 Aldosterone Receptor Antagonist 3 Beta Blocker 4 Digoxin 5 Loop Diuretics . d Contains data obs: 14,877 vars: 5 size: 312,417 (99.8% of memory free) (_dta has notes) ------------------------------------------------------------------------------------------------------------------------------- storage display value variable name type format label variable label ------------------------------------------------------------------------------------------------------------------------------- pat_id str9 %9s PT ID_j byte %31.0g class2 Corresponds to med group in Table 1
