Preserving lists in a function

By definition, the values associated with each variable in the lists would be the default unless the user impute a different value while executing the function. But a problem arises when a variable in the list is left out completely (not...

Multiple tables
Dear list,
I have a set of 100+ variables. I would like to have one by one crosstables for each variable. I started with
table(variable1, variable2)
table(variable1, variable3)
table(variable1, variable4)
...
table(variable2, variable3)
table(variable2, variable4)
...
It seems rather tedious.
Any better ideas around?
Thanks for any help!

Dear R experts,
I would like to please ask for your help with repeating steps in an apply

Categorical variable in a custom nonlin function with gnm
Hi all
I want to construct a generalised nonlinear model (binomial family) using gnm, of the form:
Response = a + b variable1 + c variable2 + d variable3 - d b variable4 - d c variable5,
with the parameters b, c, and d appearing more than once. Hence, I think I need to use a custom nonlin function with gnm.
One of my predictor variables is categorical, so I have created a dummy variable for each factor level (i.e. zeros and ones), and incorporated each of these v...

t.test in a loop
Hi All,
I've been having a little trouble with creating a loop that will run a a
series of t.tests for inspection,
Below is the code i've tried, and some checks i've looked at.
I've used the get(paste()) idea as i was told previously that the use of the
eval should try and be avoided.
I've run a single syntax to check that my systax is correct and works
without any problems
