It is isn't easy to write code that works with column names that have spaces.
You could rewrite rpart, or just rename the columns in your data frame to work

OK, a couple of things (I only looked through quickly):
1. R doesn't allow variable names to begin with a number. Be sure you don't
try that.
2. What's the overall goal here? Read them in, change the name, then write
them out? Let us know and it will be easier to help you.
3. Regardless
Look at
?predict.glm
mydata.glm - glm(formula = Death ~ Temperature, family = binomial(link =
logit),
data = mydata)
and see that predict(mydata.glm, type=response) gives the predictions on
the probability scale.

It's because those are character strings and they are sorted lexically
(i.e., alphabetically). I think you probably can get what you prefer
by using the mixedsort/mixedorder functions of the gtools package.
Take a look at this

And the rest is
Forgive me if this is a trivial question, but I couldn't find it an answer
in former forums. I'm trying to reproduce some SAS results where they set
two parameters equal. For example:
y = b1X1 + b2X2 + b1X3
Notice that the variables X1 and X3 both have the same slope and the
intercept has been
I don't know how it ties into the tools car gives you, but one (quick
and dirty) way to do this is to simply regress on
Y ~ aX2 + b(X1+X3)
or in R code something like:
lm(Y ~ X2 + I(X1+X3), data = data.set)
which gives a linear model you can play around with. Note the I()
function [that's the
I have know how to sort and filter and group.
can anyone answer my another question?
Is there any function in R like *lead *and *lag * in SQL. They are relative
position function. We can use them to solve problem such as : on
year-on-year basis, link relative ratio
can anyone give a tips?

??lag
at the R command line.

Kel,
in addition, and depending on how you define similarity, you might want to
look into the RV coefficient as a measure of it (it is actually related to a
correlation, so similarity would rather mean similar information though not
necessarily small Euclidean distance); coeffRV in FactoMineR
Hi everyone,
I am using the fastgreedy.community function to get the $merges matrix and the
$modularity vector. This serves my purpose of testing modularity of my graph.
But I am greedy to plot the heat map and dendrrogram based on the $merges
dendogram matrix. I know that heatplot does the
88 matches
