...r, when I use this code in Unix, I can never find the file "out.tex". I assumed that R would send the file to whatever directory I was working in, but that does not seem to be the case. So, I tried specifiying the exact location where I want the file: latex(Estimates, file='/home/b/bquinif/bq/9095/out.tex', rowlabel='',digits=3) When I do that, I get an error message sayin that the file/directory does not exist. I have written lots of files from Stata to locations specified like above, so I don't understand what's going on. Can anyone help me straighten this ou...

Thanks to the help of many on this list, I am now an R user and have been able to write some functioning code to do matching estimation. I have two for loops (i in 1:3, and j in 0:2). Within the loops, I had been creating matrices of relevant estimation coefficents in order to make lots of LaTeX tables. Well, now I want to be able to combine the results of many different estimations from within

Perhaps someone will have a solution to my more general problem, but here is the specific one: I used the round() function to round some estimates to 3 decimal places. I then sent put the rounded estimates in a matrix and used latex() to make a LaTeX table from them. However, in my table, there are estimtes which only have 2 decimal places. I assume that the third decimal place in these numbers

Dear R users, I am trying to become a convert to R (from Stata), and I'm having some growing pains. Is there anyone would be willing to answer a few basic questions I have? Of course I am using the relevant help guides... Thanks, Brian Quinif ps. If there is anyone at UGA on this list, I'd love to hear from someone local.

I have a question about how to reference variables in a dataframe. Normally, after I have read in some Stata data using the following command all <- read.dta('all.dta') Whenever I want to use the variable "sat.vr1" in the "all" data frame, I do so using all$sat.vr1 However, I'd like to be able to use the sat.vr1 variable without the "all$" (as well

I would like to use a for loop to run estimations on 12 different subsets of a dataset. I have the basics of my script figured out, but I am having problems getting the loop to name some files as I would like. Here is a sketch of my code: sub.dataset <- c(101, 201) #Assume I only have two subsets which I call 101 and 201 for (i in 1:length(sub.dataset)) { #Estimation commands

When I try to install hte Econometrics view I get the following error: CRAN task view Econometrics not available in: install.views("Econometrics") I have already install the ctv package and loaded it before trying to install the above... Any ideas as to what's going on?

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 there anyway to make a for loop that uses all four years at once, then uses each individual year?

Consider this: > y <- matrix(1:8, ncol=2) > is.matrix(y[-c(1,2),]) [1] TRUE > is.matrix(y[-c(1,2,3),]) [1] FALSE > is.matrix(y[-c(1,2,3,4),]) [1] TRUE It seems like an inconsistent behaviour: - with 2 or more rows we have a matrix - with 1 row we do not have a matrix and - with 0 rows we have a matrix again I just stumbled on this behaviour, because I had a problem with my

I have found out that the way to have a break apart a long caption in the way that one desires is to have a short caption for use in the list of tables that is not broken with \\ I can manually adjust the LaTeX output from the Hmisc function latex() to get the tables how I want them. However, I would like to automate the creation of these tables. Inside the latex() function, I tried this:

I am sorry to ask such a simple question, but my knowledge of programming language is extremely limited, and I couldn't find the answer in any of the normal resources. I want to do a for loop in which m takes on the values 1, 5, 10, 15, 20. What is the syntax for doing that? I had been doing a loop for m in 1:20, but I only want those values above. Thanks, Brian

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 something like that. On a related note, if anyone knows how to get the end result I want

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 significantly. I want to use the heteroscedasticity consistent std. errors in my project, but as long

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 without having to do much more work, if possible. Thanks, Brian

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.... Thanks, Brian

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))) oldClass(object) <- data.class(object) UseMethod("latex") } What should I do?

I am ashamed to be asking this question, but I couldn't find the solution anywhere. Searching for "if" and "R" is not very productive... I cannot get a simple if statement to work. I have data on college students. I want to make a string variable that has the names of the years. That is, when the year variable i is equal to 1, I want to have a variable called years

Dear R users, I am using the Match function to generate nearest neighbor matching estimators. On that front I am ok, but where I am having problems is getting my output into nice LaTeX tables. Here is some basic code imitating the estimation I'm doing. No problem there. library(Matching) #make up some data X1 <- matrix(rnorm(1000*5), ncol=5) Y1 <- as.vector(rnorm(1000)) Tr1 <-

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 you use (this is the Var.cal option). It seems to me that it might make sense to use the same number
