# [R] applying a set of rules to each row

```If I understand you correctly, you want ?ifelse, which works on the
full logical vectors of rules applied to the variables, not
if....else, which works on only a single logical.

> The data set has four variables Date of Birth (DOB), service computation
> date (srvCompDT), retirement plan (retirePlan), and the age at which the
> employee entered federal service (ageFedStart). The service computation
> date is used to compute the date eligible for retirement. The retirement
> plan indicates what system the employee is enrolled under.
>
> The data does contain a few other retirement plans, for now I want to
> just ignore those plans. I have labeled plans as 1-CSRS and 2-FERS, and
> 3-Other. My first attempt at applying the rules was through a complex
> nesting of ifelse statements, this was not very successful and quite
> difficult to follow. I then wrote a function and tried using "apply"
> unsuccessfully. The function is shown below.

> rules would be quite helpful.
