use function on several variables

[Sybille de Madre]

Hello everyone,

I want to apply a function to several variables but haven't found a solution.

I have 14 variables : IRIS P19_LOG P19_RP P19_LOGVAC P19_MEN P19_MEN_ANEM0002 P19_PMEN P19_PMEN_ANEM0002 P19_RP_PROP P19_RP_LOC P19_RP_LOCHLMV C19_RP_HSTU1P C19_RP_HSTU1P_SUROCC
IRIS is the id. I want to change the value of the 13 other variables by their rounded value, to the closest integer.

replace var=round(var, 1)

do i need to make 13 lines as such : replace P19_MEN=round(P19_MEN, 1),... or is there a shorter way ?

Thanks a lot!!!

foreach v of varlist P19_LOG P19_RP P19_LOGVAC P19_MEN P19_MEN_ANEM0002 ///
P19_PMEN P19_PMEN_ANEM0002 P19_RP_PROP P19_RP_LOC P19_RP///
_LOCHLMV C19_RP_HSTU1P C19_RP_HSTU1P_SUROCC {
    replace `v' = round(`v', 1)
}

If in fact those 13 variables are the only variables in the data set other than IRIS, you can do this even more economically as:

ds IRIS, not
foreach v of varlist `r(varlist)' {
    replace `v' = round(`v', 1)
}
