Dear All, I am given a set of files names as: velocity1.txt velocity2.txt and so on. I am sure there must be a way to read them automatically in R. It is really taking me longer to read them than to analyze them. Anybody has a suggestion to help me out with this? Many thanks Lorenzo

Hello R community: I'm encountering unexpected behaviour as I download string data from MySQL using the RODBC package. The unexpected behaviour is that the last character of the string is truncated. As far as I can see, this happens when some strings are of length 501 or more. Here's how to reproduce this behaviour. ## In MySQL, pick a database and run this: CREATE TABLE test ( v1

When updating to the very last version of RODBC under freebsd 6.1 the errors below pop up but RODBC compiles till the end and, it seems, to work properly. What are those errors about? Vittorio .............................................. checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... grep: error while

In a mdb table, I have a text field with values of 1, 2, .... When I use rodbc to read it into R, it becomes numeric. Is it a bug or something? Thanks.

Hello, I'am currently experiencing some problems with the odbcCloseAll() and odbcClose() function. I'm trying to connect an R script to a MySQL 5.0 database using RODBC1.1-7 and the MySQL ODBC Driver v.3.51 on a Windows XP Machine. At first everything seems fine. The script connects, reads and writes data but when it comes to odbcCloseAll() it crashes and hangs forever. Unfortunately I

Hi. I am trying to get data from mysql database using a couple of queries. I do one query to find out the indexes. Then i need to use these indexes in another query, but i keep getting errors. Here is something: numb <- dbSendQuery(con2, "select distinct(comparison) from table1") count <- fetch(numb, -1) my.matrix <- as.matrix(count) rs <- dbSendQuery(con2, "select

I think I asked a similar question 3 years ago to the Splus list and I think the answer was no or noone answered so noone should spend more than 5 minutes on this because it could definitely be a waste of time. My question is whether the function below can be rewritten without a for loop. apply is fine if it can be done that way but i doubt it. I call it a lot and would prefer to not loop.

Dear list # I have a function ff <- function(a,b=2,c=4){a+b+c} # which I programmatically want to modify to a more specialized function in which a is replaced by 1 ff1 <- function(b=2,c=4){1+b+c} # I do as follows: vals <- list(a=1) (expr1 <- as.expression(body(ff))) expression({ a + b + c }) (expr2 <- do.call("substitute", list(expr1[[1]], vals))) { 1 +

Hi dears, I expect that Mr Thomas Lumley will read this message. I have data from a complexe stratified survey. The population is divide in 12 regions and a region consist to and urban area and rural one. there to region just with urbain area. stratification variable is a combinaison of region and area type (urban/rural) In rural area, subdivision are sample with probabilties proporionnal to

Hi R people: On page 235 of the Blue Book (Becker, Chambers, and Wilks), there is a "compose2" function. compose2 <- function(f,g) { gg <- substitute(g1(x)) print(gg) gg[[1]] <- g ff <- substitute(f1(y)) print(ff) ff[[1]] <- f ff[[2]] <- gg print(ff) fun <- function(x){ NULL } fun[[2]] <- ff fun } However, when I run this function using sum

Hi all, How can I overcome the error "object of type 'closure' not subsettable" I ran the following script seq <- paste(seq(1914, 1916, by=1), "*.y", sep=".") # make sequence c <- 3 # total number of files d2 <- file # creates dummy file # Input sequence in loop for (i in 1:3){ list <- list.files("~/ukcp09/txt/x.djf", seq[[i]]) file

Dear all, One of my students (whom I am trying to convince to use R) wants to get a fairly large SAS dataset into R (about 150mB). An obvious and simple thing she tried was to write the dataset as a .csv-file and then read that into R, but that takes forever (or something close to that..). The dataset is so large, that exporting it as an Excel file from SAS is not feasible (more than 65000 lines).

Dear all, In SAS (GLM and MIXED) estimable functions (linear functions of the parameters) can be specified in the ESTIMATE and CONTRAST statements. Has anyone written a similar "utility" for use in connection with lm?

I have been using R and Perl. When I read in a text file using the read.table option, and I try to mathematically manipulate the individual elements in the table, I keep getting an "object is not subsettable" error. If I try to use a different method, it works, but takes too much time(basically, I then need to read in values individually into R instead of as a 2D array, so the number of

Dear all, I was trying to see how the function 'confint' is defined. Doing > confint function (object, parm, level = 0.95, ...) UseMethod("confint") <environment: namespace:stats> does not really enlighten me. How can I get to see the implementation (I guess it should be possible according to the general philosophy of the R project)? Thanks in advance S??ren

Dear R-users I need to calibrate kappa, rho, eta, theta, v0 in the following code, see below. However when I run it, I get: y <- function(kappahat, rhohat, etahat, thetahat, v0hat) {sum(difference(k, t, S0, X, r, implvol, q, kappahat, rhohat, etahat, thetahat, v0hat)^2)} > nlminb(start=list(kappa, rho, eta, theta, v0), objective = y, lower =lb, > upper =ub) Error in dots[[1L]][[1L]] :

Thanks. I wonder if there is a general way of extracting var(u) and var(e), which would be needed to simulate u and e. Clearly, one can get the estimated parameters, but is there a clever way of 'setting up' the matrices??
