similar to: Cannot clean infinite values

Hello all, I have to import numeric data from file but found it contains Infinite values which need to be eliminated. I tried to replace them in this way: data[which(data=="-Inf")] <- -0.3 data[which(data=="+Inf")] <- 0.3 But, somehow, the Infinite values stayed there. Any suggestions? regards, N. -- View this message in context:

Hi, I am trying to do a PCA on my data but I keep getting the error message svd(x, nu=0) infinite or missing values >From the messages posted on the subject, I understand that the NAs in my data might be the problem, but I thought na.omit would take care of that. Less than 5% of my cells are missing data. However, the NAs are not regularly distributed across my matrix: certain cases and

Hello, I am trying to run an ordinal logistic regression (polr) using the package 'MASS'. I have successfully run other regression classes (glm, multinom) without much problem, but with the 'polr' class I get the following error: " Error in svd(X) : infinite or missing values in 'x' " which appears when I run the "summary" command. The data file is

Dear r-help, I want to use tapply to calculate means for a variable. But there were several infinite values in the observations. How can I calculate means not considering these infinite values? Thanks in advance. Regards, Lei [[alternative HTML version deleted]]

Dear all, I am running an Ecological Niche Factor Analysis in R but I am stuck with a problem. As soon as I ask the software to compute the ENFA, I get the following error message: Error in eigen(Se) : infinite or missing values in 'x' Does anyone know what could be wrong. I do not have missing values in my dataset. Please follow the codes I used for my analysis so far: library

an error in my rails code caused the framework to send an infinite number of SQL calls to the database. I killed the webrick server, restarted postgres, deleted the /tmp file in my rails application, deleted the bad code, restarted firefox, restarted the webrick server. All to no avail. As soon as I try loading my application, the infinite recursion starts again. I can no longer work. This

I have a data.frame named "df". The dput of df is at the bottom of this e-mail. What I'd like to do is replace the "n/a " values with NA. On Mac OSX, it works to do this: df[df == "n/a"] <- NA However, it does not work on Ubuntu. See below. Thanks in advance, Garrett > x <- df[27, 4] # complete data.frame dput is below > dput(x) "n/a?"

Hi everyone.

Dear R-users, I'm estimating a two- dimensional state-space model using the FKF package. The resulting log likelihood function is maximized using auglag from the Alabama package. The procedure works well for a subset of my data, but if I try to use the entire data set I get the following error message. Error in eigen(a$hessian) : infinite or missing values in 'x' What's even

Hello, All: I have a 4.54 GB file that I'm trying to read in chunks using "scan(..., skip=__)". It works as expected for small values of "skip" but goes into an infinite loop for "skip=1e11" and similar large values of skip: I cannot even interrupt it; I must kill R. Below please find sessionInfo() with a toy example. My real problem is a large

You are correct in your expectations. This is a bug: the C code does not cover the cases +/-Inf (because it uses R_FINITE to exclude them). I'll fix it in R-patched: filing with R-bugs for the record.

I ran into a problem recently trying to update a package which uses S4 methods using a recent beta of R. I think I can reproduce it with a simple example. I have package called `testpkg' in directory testpkg/. In the R/ subdirectory of testpkg/ I have a file called testpkg.R which contains the following two lines: setClass("testpkg", representation(pts = "list"))

Following loop (in asm) is often seen in embedded programs. It is used to delay for certain amount of time. If it were not written in asm, compiler would blindly delete the entire loop. How can compiler know such DCE betray program intention? for (i = 0; i < N; i++) { nop; nop; nop } I guess in the gray area, if programmer do not want compiler do something he doesn't expect, he/she

I am doing work on changes in establishment sizes and came across behavior that is quite understandable and easily worked around but a little surprising.
