Suppose you're reading data from a file in which the column names contain underscore characters. Example: ------ start of file ----- pos_x pos_y 1.0 0.0 2.0 1.0 ------ end of file ------- Using read.table, I can read this file just fine: > data <- read.table (file="data", head=T) > data pos_x pos_y 1 1 0 2 2 1 > However, I can't

How does one specify the weights for WLS in the systemfit command ? That is, there is a weight option in lm(), but there doesn't seem to be weight option for systemfit("WLS") Thanks!

You need to specify sub-register == super-register, idx relationship. See X86RegisterInfo.td: def x86_subreg_8bit : PatLeaf<(i32 1)>; def x86_subreg_16bit : PatLeaf<(i32 2)>; def x86_subreg_32bit : PatLeaf<(i32 3)>; def : SubRegSet<1, [AX, CX, DX, BX, SP, BP, SI, DI, R8W, R9W, R10W, R11W, R12W, R13W, R14W, R15W], [AL, CL,

Dear All, I've been trying to run a Weighted Least Squares (WLS) regression: Dependent variables: a 60*200 matrix (*Rit*) with 200 companies and 60 dates for each company Independent variables: a 60*4 matrix (*Ft*) with 4 factors and 60 dates for each factor Weights: a 60*200 matrix (*Wit*) with weights for 200 companies and 60 dates for each company The WLS regression I would like to run

1) Is it possible to erase data points, legends, and/or text from an R plot? 2) What's the best way to find the closest data point to what locator() returns? For more background and some context on these questions, read on... In using R interactively, I am displaying further details about a specific data point when the user clicks on the plot point. Here's a simple example: #

I am using R on a Windows XP professional platform. The following code is part of a bigger one CODE press=function(y,x){ library(qpcR) models.press=numeric(0) cat("\n") dep=y print(dep) indep=log(x) print(indep) yfit=dep-PRESS(lm(dep~indep))[[2]] cat("\n yfit\n") print(yfit) yfit.orig=yfit presid=y-yfit.orig press=sum(presid^2)

I would like to obtain Confidence Intervals for the estimates (unstandardized beta weights) of each predictor in a WLS regression: m1 = lm(x~ x1+x2+x3, weights=W, data=D) SPSS offers that output by default, and I am not able to find a way to do this in R. I read through predict.lm, but I do not find a way to get the CIs for multiple independent variables. Thank you Torvon [[alternative HTML

R 1.6.2 for Windows, Win2k: I have fitted a weighted least squares model using the code "wls.out <- gls(y ~ x1 + x2 + x3 + x4 + x5 + x6 - 1, data = foo.frame, weights = varConstPower(form = ~ fitted(.), fixed = list(power = 0.5), const = 1))" The data has 62 rows and the response is zero when the covariates are zero. The purpose of the model was to account for the the fact that

Task: To generate HTML output from R Details: I am trying to serve up HTML output from R. That is analyses or table of data from R saved as HTML output with formatted tables etc. This file is then called in a CGI script to output to user browser. The CGI script inspired by Mark J. Ray reads the HTML output, formats the header and footer and any graphic output if necessary. My question is: Has

In my ISA, some registers are write-only. These registers serve as output ports, writing to these registers will output the values to an external device. They cannot be read. So their live intervals should not be joined with any other registers. The only way I know to do this is defining several instruction 'templates' for an opcode (of course automatically generated by a script) similar
