Supplement 2. Scripts and data for estimating quantile equivalence of the vegetation reclamation data (Manly 2004) with the quantreg package in R.
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
manlyveg.rtf is a text file with commands for implementing the quantile regression analyses on the vegetation reclamation data in the text file manlyveg2.csv using the quantreg package in R.manlyveg2.csv
Column 1: VEGPROD - vegetation production in g/m^2,
Column 2: SITE - an indicator variable with a 1 for reclaimed and 0 for control sites,
Column 3: LNVEGPROD - natural log of vegetation production,
Column 4: WT - weights used in analysis.
