Error message with glm
I'm working on a logistic regression in R with the car package but keep
getting the following error message.
It's only and warning and not an error, but I'm just not sure how to
resolve the issues.

Using the effects package to plot logit probabilities
I'm trying to run a logit model and plot the probability curve for a number
of the important predictors. I'm trying to do this
with the Effects package.

Plotting the probability curve from a logit model with 10 predictors
I have a logit model with about 10 predictors and I am trying to plot the
probability curve for the model.
Y=1 = 1 / 1+e^-z where z=B0 + B1X1 + ... + BnXi
If the model had only one predictor, I know to do something like below.
mod1 = glm(factor(won) ~ as.numeric(bid), data=mydat,
family=binomial(link="logit"))
all.x <- expand.grid(won=unique(won), bid=unique(bid))

remove all "|" values from the START of the string. So they should

Reordering a numeric variable
I'm running a linear model in R using the car package.
I have a variable education, which i have recoded and regrouped to my
wishes.
However, R seems to place each element of that variable in alphabetical
order.
When I am running the model, don't I need the model order from lowest to
highest to make an inference that

Predicting a linear model for all combinations
Lets say I have a linear model and I want to find the average expented
value of the dependent variable. So let's assume that I'm studying the
price I pay for coffee.
Price = B0 + B1(weather) + B2(gender) + ...
What I'm trying to find is the predicted price for every possible
combination of values in the independent variables.
So Expected price when:
weather=1, gender=male

Calculating percentages across multiple columns
I have the following data and am trying to find the percentage of bid
values purchased for that price.
So let's say I have a bid of 5 and it's sold 2 times for $3 and $5. Since
the original bid was $5, the
percentage of times that that bid value results in a sold purchase AT that
specific bid level was
1/3 because of the three time where the bid was three, it ended up being
sold for $5

Plotting every probability curve
I don't have a logistic regression model and am trying to generate
probability curves for all possible combinations of
the variables. My logit model has 5+ variables, and I want to draw curves
for every scenario.
See code below. When home_owner is 0 and 1, I want curves. The same goes
for all other variables categories, so that
I have permutations for all possible combinations.

read.xls question
I'm an R newbie and had a question about the read.xls function. I've heard that this is often not a reliable function to use for importing data. However, I have created numerous xls files which contain information about voter turnout and macroeconomic indicators in India. I'm writing a paper on the relationship between economic growth and voter turnout.
This is the command I use:

Finalizer execution order question
Given an externalptr object 'pool' which protects an R object 'prot':
# SEXP prot = (a dynamically updated list with handles)
SEXP pool = R_MakeExternalPtr(p, R_NilValue, prot);
R_RegisterCFinalizerEx(pool, fin_pool, TRUE);
WRE explains that 'prot' remains in existence as long as 'pool' is
around. Does this also mean 'prot' still exists when the
