panel2cs2 takes a 2 period dataset and turns it
into a cross sectional dataset; i.e., long to wide.
This function considers a particular case where there is some outcome
whose value can change over time. It returns the dataset from the first
period with the outcome in the second period and the change in outcomes
over time appended to it
Usage
panel2cs2(data, yname, idname, tname, balance_panel = TRUE)
Arguments
- data
data.frame used in function
- yname
name of outcome variable that can change over time
- idname
unique id
- tname
time period name
- balance_panel
whether to ensure that panel is balanced. Default is TRUE, but code runs somewhat
faster if this is set to be FALSE.
Value
data from first period with .y0 (outcome in first period),
.y1 (outcome in second period), and .dy (change in outcomes
over time) appended to it
