similar to: retrieving last R output

I have a list of vectors of length 2, each representing a point in 2-space, and each of which I wish to plot on the current plot. In a loop, I assign the x and y coordinates of the current element of the list to variables 'x' and 'y' respectively, then make a call to plot as follows: par(new = TRUE) plot(x,y, xlim = c(0,1),ylim=c(0,1), xlab <- "x", ylab <-

Consider the following code: test <- function(n) { for(x in 1:n) { for(y in 1:n) { for(r in max(x-1,1):min(x+1,n)) { for(s in max(y-1,1):min(y+1,n)) { vec <- c(x-r,y-s) print(c("vec = ", vec)) print(identical(vec,c(0,0))) } } } } } If you run test(2) you'll see a printout of the values

Hello. I've observed some odd behaviour. Most likely, it is already known and explained somewhere, but I can't find an explanation anywhere, so I would appreciate being pointed in the right direction. The issue with the following code is self explanatory: > mat <- matrix(c(c(1,1,1),c(2,2,2)),nrow=3) > mat[,c(1:3%/%2)] [,1] [,2] [1,] 1 1 [2,] 1 1 [3,] 1 1

Hello. I have a 4 dimensional array and I want to fill in the slots with values which are a function of the inputs. Through searching the forums here I found that the function "outer" is helpful for 2x2 matrices but cannot be applied to general multidimensional arrays. Is there anything which can achieve, more efficiently than the following code, the job I want? K <-

Hi, I have a large table in Postgresql (result of an MCMC simulation, with 1 million rows) and I would like to retrive colums (correspond to variables) using RODBC. I have a column called "index" which is used to order rows. Unfortunately, sqlQuery can't return all the values from a column at once (RODBC complains about lack of memory). So I am using the following code:

I can't find a way to retrieve z values and p-values from the output from lmer in the lme4 package. How is this done? Rick B.

Hi folks, I'm stuck with a problem that I suspect has a trivial solution... I have a function, call it foo, that takes a number of arguments which it uses as parameters for a simulation. For later analysis, foo stores the names of the objects passed to it along with the simulation results in its output (written to a database). The objects names are accessed with deparse(substitute(argname)).

Hi All: I need to run a bunch of models one-by-one and retrieve the outputs (like estimates, p values) accordingly. Some of models may not have outputs due to singularity or even no observations. If this happens, assign NA to the outputs. For example, #running models fit.mod <- lm(xxxxxxxxxx) #model 1 fit.mod <- lm(xxxxxxxxxx) #model 2 ......... fit.mod <- lm(xxxxxxxxxx) #model 10

Colleagues, I am using "nls" successfully (2.11.1, OS X) but I am having difficulties retrieving part of the output - residual sum of squares. I have assigned the output to FIT: > > FIT > Nonlinear regression model > model: NEWY ~ PMESOR + PAMPLITUDE * cos(2 * pi * (NEWX - POFFSET)/PERIOD) > data: parent.frame() > PMESOR PAMPLITUDE POFFSET >

Dear R Gurus, As you probably know, dist calculates the distance between every two rows of data. What I am interested in is the actual two rows that have the least distance between them, rather than the numerical value of the distance itself. For example, If the minimum distance in the following sample run is d[14], which is .3826119, and the rows are 4 & 6. I need to find a generic way to

Does anyone have any experience retrieving latitutde and longitude for an address from the Google Maps API? I'd like to have an R script that submits a street address, city, state, and zip code and returns the coordinates. So far, I've been submitting the coordinates from another program, then loading the coordinates in R and merging them back into the data frame I want to use.

Is this something that will happen in future? Or there is no plan for it?

Hi, this is probably a very trivial question but I can't figure out the right terms to find the solution in the list archive. I have a matrix or a data.frame or the like: > m <- matrix(ncol=3,seq(1,9)) > m [,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9 and now I wonder if one can provide somehow two vectors, one containing row numbers, the other

Hello Everyone, I need some help in retrieving the numeric value of an instruction operand from LLVM IR. this is what the IR looks like for a simple add function that adds two i32 integers define i32 @summ(i32 %a, i32 %b) #0 { entry: %add = add nsw i32 %b, %a ret i32 %add } i would like to know the integer value of %a and %b. I've tried -i->getOpcodeName() which gives me the

I need people to answer a survey super quick for the next little release of Mongrel. Basically, nobody ever agrees on mime types, especially defaults, which is why Mongrel has none and you set your own. Sometimes people just refuse to set their own and want Mongrel to do everything for them, but if that happens then people will complain about the defaults. Damned if I do, damned if I

Hello, I need to retrieve datas from bloomberg. I want to retrieve those datas in the fastest way as possible. I have two options: writing the datas from bbg to excel and reading from r the excel sheet or directly read the datas from from r with a Rbbg connection. Which connection is faster?

Hi all, So let's say I have a matrix, mdat and I only know the index number. How do I retrieve the column and row names? For example, > mdat <- matrix(c(1,2,3, 11,12,13), nrow = 2, ncol=3, byrow=TRUE, dimnames = list(c("row1", "row2"), c("C.1", "C.2", "C.3"))) > mdat[4] [1] 12 >
