Hi, I used RODBC to import data from an Excel spreadsheet "*.xls", but some columns were returned as zeros. When I looked at these columns in Excel, I found that thery are results of formula calculations and not entry. My question is: Is there any parameter or command I need to use in order to overcome this problem? Thank you Ahmad Abu Hammour

Hi, P-values in Durbin-Watson test obtained through the use of functions available in packages "lmtest" and "car" are different. The difference is quite significant. function "dwtest" in "lmtest" is much faster than "burbinwatson" in "car". Actually, you can take a nap while the latter trying to calculated Durbin-Watson test. My question

Full_Name: Ahmad Abu Hammour Version: rw0651 OS: windows 95 Submission from: (NULL) (63.23.128.44) Although I know that "ts package" is preliminary, I wanted to compare the results from R and SPSS. I ran ARIMA(2,1,2) in both softwares. I got NaN in standard errors of coefficients from R and real figures from SPSS. I changed "delta" in R to match that used by SPSS, I received

Hi, Is there a function in any of R-packages that can produce and plot the impulse response function for any model..

Hi all. I have unexpected reshape results on datasets with certain variable names. Here a reproducible example: d <- matrix(seq_len(7*7), 1, 7*7) vnames <- c('acc','ppeGross','CF','ROA','DeltaSales','invTA','DeltaRevDeltaRec') varying <- unlist(lapply(vnames, paste, 1:7, sep='.')) d <- data.frame(d) names(d) <- varying

I'm trying to use Rprof() to identify bottlenecks and speed up a particullary slow section of code which reads in a portion of a tif file and compares each of the values to values of predictors used for model fitting. I've written up an example that anyone can run. Generally temp would be a section of a tif read into a data.frame and used later for other processing. The first portion

Hi, I have the following hypothetical optimization problem: -det(t(x-A%*%x1)%*%(x-A%*%x1)) where A,x,x1 are matrices. A coefficients and x and x1 are variable matrices or vectors. I tried to apply optim and nlm functions but I kept receive the following massage: Error in A%*%x1 : non-conformable arguments. The massage appears even the -det() can be calculated and the dimensions are checked. here

Hi, I am using R interactively for estimation and even data manipulation. I want to use lag() function within lm() function in a way looks like: mymodel<- lm(y~x+I(lag(y,-1)-1, data=anydata) What I get is always perfect fit; (that is, coefficient=1) which is not true. If the model looks like mymodel<- lm(y~z+x+I(lag(x,-1)-1, data=anydata) summary returns only one coefficient for x and

I am trying to analyse some data and was given R code to do this with but there seem to be errors in the code. My level of knowledge is improving but still limited. The details are; Data on clover lines; Lines.txt attached. Comma seperations Code: options(digits=3) clover <- read.table("Lines.txt",header=T,sep=",") vnames <- names(clover);nv <- length(vnames)

Hi, I have a matrix and time series "xmat". I have no problem executing any matrix functions except t(xmat) which gives the following error message. My question if "xmat" is a matrix why I can not execute this matrix function?? converting the time series and matrix into a data frame solves the problem >dim(xmat) [1] 98 7 > t(xmat) Error in "tsp<-"(*tmp*,

Hi, I need help regarding estimating a linear model where restrictions are imposed on the coefficients. An example is as follows: Y_{t+2}=a1Y_{t+1} + a2 Y_t + b x_t + e_t restriction a1+ a2 =1 Is there a function or a package that can estimate the coefficient of a model like this? I want to estimate the coefficients rather than test them. Thank you for your help Ahmad Abu Hammour --------------

Hello, Summary: "samba-tool domain join" doesn't seem to work if you pass both "-k yes" and -U. Samba version: 4.9.5-Debian I have a newly-provisioned AD domain with a single DC (dc1). I'm attempting to join a second DC (dc2), per the wiki. On dc2: - I have /etc/resolv.conf pointing at dc1 (confirmed all AD DNS resolution works) - I've copied the basic

Dear R Help Please forgive my lack of knowledge,.I would be very thankful for some help. Here is my problem: I was using optim to estimate parameters of a model and I get this error message "Error in optim(x0, fn = riskll, method = "L-BFGS-B", lower = lbs, upper = ubs, : L-BFGS-B needs finite values of 'fn'" Below is the R code I have written.

The driver doesn't consider framebuffer pitch and offset, leading to a wrong display in case offset != 0 or pitch != width * bpp. Fix it.

Hi there, when plotting a time series I got this error message: Error in xy.coords(x, y, xlabel, ylabel, log) : x and y lengths differ In addition: Warning messages: 1: longer object length is not a multiple of shorter object length in: vx.1[int.lr] + (-1) * vx.2[int.rl] vx.1[int.rl] and vx.2[int.rl] have the same length. Does anybody know what the warning message means? Thanks, Sven

Dear R developers, A great R feature is that elements of vectors, lists and dataframes can have names: vx = c(a=1, b=2) lx = list(a=1, b=2) Accessing element "a" of vx: vx['a'] Accessing element "a" of lx: lx[['a']] or lx$a Might be a matter of taste, but I like the $ very much. Unfortunately, vx$a is not functional. Would it break existing compatibility

Greetings, Q #1 ------ How does one combine data frames by row ... no cleverness a la merge(), just add rows. For example, given A with 20 rows and B with 30 rows, I want C = combine( A, B) having 50 rows. Columns having matching names should be filled from both (all) sources with suitable coercion, unmatched would get NA in rows whose source does not have that column. Q #2 ------ Given
