I think that the easiest for you would be to keep your current elseif

In this code, I assume that your data are stored in the variable

I don't know the dataset at all (and you seem to assume that your

Katherine,
Split the rate names into their currency and tenor parts and assign a
numeric value to each tenor. Choose a model to do your approximations (I
used linear regression in the example below). Use this model to generate
estimates for all combinations of currency and tenor.
For example:
First you should read some introductory manuals on R. There are many to
choose from at
http://cran.r-project.org/other-docs.html
For example, your first question is very simple:
z - data.frame(a, b, c)
To draw a single random sample (with replacement) from z:
z1 - z[sample(1:nrow(z), nrow(z),
Another approach:
x[1:length(x) %% 10 == 0] - NA
Just replace 10 by the interval you want. Or to add 5 missing values
randomly:
x[sample(1:length(x), 5)] -NA
