Lab position using filter (if)

[Rodrigo Badilla]

Hi all,

I wondering if its possible use lab position using 2 diferents filter, example:

clear all
set more off
sysuse auto
collapse mpg, by(rep78)
drop if missing(rep78)

scatter  mpg rep78, ///
c(l) sort ///
mlabel(mpg) ///
mlabposition(6)

My goal its use filters to lab position, do you know if its possible?, example:

scatter  mpg rep78, ///
c(l) sort ///
mlabel(mpg) ///
mlabposition(12 if rep78> 2) ///
mlabposition(6 if rep78< 2)

Thanks in advance.
Rodrigo

You can use the -mlabvposition()- option to specify the position for each point:

sysuse auto,clear
collapse mpg, by(rep78)
drop if missing(rep78)
gen pos = 12 if rep > 2
replace pos = 6 if rep <=2

scatter  mpg rep78, ///
    c(l) sort mlabel(mpg) mlabv(pos)

Thanks Scott Merryman for you reply!

In the same side:

I am trying to alternate position label (pos=6 and pos=12) in the graph, for this purpose I am trying to generate sequential dicotomic variable.

For this purpose I am using labvposition package.

Code example:

sysuse auto,clear
collapse mpg, by(rep78)
drop if missing(rep78)
gen pos = 6
replace pos = 12 if pos in 1/1
replace pos = 12 if pos in 3/3
replace pos = 12 if pos in 5/5

scatter  mpg rep78, ///
    c(l) sort mlabel(mpg) mlabv(pos)

Do you know other way to generate sequential dcotomic variable?
Thanks in advance

egen pos = fill(12 6 12)

[Nick Cox]

gen pos = cond(mod(_n, 2), 12, 6)

Thanks Nick Cox and Scott Merryman , both command works fine!
