[R] code for latex function in Hmisc

Forgive my ignorance, but how I can take a look at the code for the latex function in the Hmisc library? I tried just typing latex but all I got was this: latex function (object, title = first.word(deparse(substitute(object))), ...) { if (!length(oldClass(object)))

[R] function for linear regression with White std. errors

I would like to know if there is a function that will run a linear regression and report the White (heteroscedasticity consistent) std. errors. I've found the hccm() function in the car library, but that just gives me the White covariance matrix. I'd like to be able to see the White std. errors

[R] displaying numbers not in scientific notation

Sorry for asking such a simple question, but I couldn't find the answer through a search... How can I get R to show me the values of estimates *not* in scientific notation? When I use summary() after using lm() I am getting numbers like 4.485107e-01, when what I want to see is 0.4485

Re: [R] number of matches when using Match()

Speaking of standard errors, when correcting for heteroscedasticity, how many matches do you use (this is the Var.cal option). It seems to me that it might make sense to use the same number of matches as above, but that's just a guess... These are related but separate issues. The

[R] Var.calc in Match()

Does anyone else find that using the Var.calc option (for heteroscedasticity consistent std. errors) in Match() (from the Matching library) slows down computation of the matching estimator by a lot? I don't really understand why when I use this option it slows down so much, but for me it does

[R] dcolumn

Does anyone out there use dcolumn=TRUE in the latex() function in the Hmisc library? I would like to line up the data in a latex table I'm making using latex(), but I'm having some issues with this feature. Since there is no description of it in the help, I thought that it might be incomplete or

[R] another very simple loop question

I have a dataset with 4 years of students, and normally I want to estimate things using each individual year, so I have a for loop as follows for (i in 1:4){} However, the only way I know how to calculate estimates using all four years of data is to put the estimations outside of the loop. Is

To anyone who uses the Match() function in the Matching library... How do you go about deciding how many matches you will use? With my data, my standard errors generally get smaller if I use more matches. Speaking of standard errors, when correcting for heteroscedasticity, how many matches do

[R] long caption titles for tables

Hi Ken, Thanks for the help, but I should have mentioned that I want to do this within a loop. Perhaps it would be better for me to explain my exact situation. I am running two loops so that I can calculate estimates for years 1,2,3,4 and a categorical GPA variable that takes on three values
