similar to: Using data( ) in a loop

I am using the code below to extract census tract information. save.tract$state, save.tract$county and save.tract$tract are returned as factors. In the last three statements, I need to save the actual value of the factor, but, instead, the code is yielding the position of the factor. How do I instead return the value of the factor? By way of example, for Lon=-82.49574 and Lat=29.71495, the code

Does anyone know the appropriate R code to obtain census tracts (tract and block level) from addresses by using Zack Almquist's USCensus2000 package? Thank you, -- Michael Leitson Michael.Leitson at gmail.com

I am having trouble getting data labels to display over the provinces in a GADM map of Canada. Specifically, I need the variable "Number" from the data set "by_province", grouped by "region", to appear on the corresponding regions of the map. The data set "by_province" looks like this: long lat order hole piece region

Hi Jay - I see the slow, small accesses using an older clang [Apple LLVM version 7.0.0 (clang-700.1.76)], but this looks fixed on trunk. I made a change that comes into play if you don't specify a particular CPU: http://llvm.org/viewvc/llvm-project?view=revision&revision=245950 $ ./clang -O1 -mavx copy.c -S -o - ... movslq %edi, %rax movq _spr_dynamic at GOTPCREL(%rip),

Well, here's one way to do it: (dat is your example data frame) Cutoff <- seq(0, .15, .01) Pop <- with(dat, sapply(Cutoff, \(p)sum(Totpop[Pct >= p]))) I think there must be a more efficient way to do it with cumsum(), though.

Hi all, I've got some functioning code that I've literally taken hours to write. My 'R' coding is getting better...it used to take days :) I know I've done a poor job of optimizing the code. In addition, I'm missing an important step and don't know where to put it. So, three questions: 1) I'd like the resulting output to be sorted on distance (ascending) and

This seems like it should be simple but I can't get it to work properly. I'm starting with a data frame like this: Tract Pct Totpop 1 0.05 4000 2 0.03 3500 3 0.01 4500 4 0.12 4100 5 0.21 3900 6 0.04 4250 7 0.07 5100 8 0.09

Hello, I am using the following code to create ppp files from csv data and map shape files, but I am getting some errors which I have been unable to fix by searching them online: library(spatstat) library(maps) library(maptools) NYC2<-readShapePoly("nybb.shp") # this is a map of the NYC boroughs without waterways and no census tract divisions (but it does include lines separating

Thank you for your reply. FWIW, I wrote the .ll by hand after taking the C program, using clang to emit the llvm and seeing the memcpy. The memcpy version that clang generates gets compiled into assembly that uses the large sequence of movs and does not use the vector hardware at all. When I started debugging, I took that clang produced .ll and started to write it different ways trying to get

Yeah, the llvm-ar tests are working on Windows. But I'm getting different results when I try to use the same commands in an LLDB lit test. Maybe there's something messed up in LLDB's local lit config? If I have `mkdir %t/subdir` in my lit test, I get either file-not-found or a complaint about "unrecognized option /subdir." The one-and-only mkdir on my PATH is

Hello! I should have asked this earlier, but... :) We're returning to voice processing in our app now, in which we're trying to achieve n-way full duplex voice in a 3d environment. Since Speex is a single voice stream CODEC, we've been looking at having each client upload its stream to the servers, which multiplex several spatially nearby active channels back down to the

I'm writing a lit test that needs to temporarily make a subdirectory. I tried: ``` // RUN: mkdir %t/subdir ``` But on Windows, it's hard to bypass the built-in mkdir to use a Posix-style one from Git or GnuWin. The built-in mkdir believes the `/subdir` is an unrecognized command flag. I figure I cannot just use a backslash because that would fail on Posix systems. (The test should

Hello, I am trying to help a colleague with an R problem (see below) to whit I can only generate a very inelegant solution. Any advice would be welcome. Thanks, Brian If you have two matrices, say a species by trait matrix (Matrix 1 below) and a plot by species matrix (Matrix 2 below), is there a straightforward way to prune one matrix so that the species list matches those in a

Hello, I was hoping someone could answer a question for me that may either be statistical or script related. I don't come from a statistics background, so I am not positive if I am using the correct nomenclature or even the correct procedure. Is it possible to model "random coefficients" in a mixed effects cox-regression using coxme from the Kinship package? For example, using
