Re: [R] HELP - as.numeric changing column data

By the way, here is an example where the advice in FAQ 7.10 (change the factor columns to numeric) would give incorrect results. The incorrect header setting in the call to read.table causes an extra row of non-numeric data to appear at the start of the imported data. > txt <- "ColA ColB\n101 1

Dear All, I can provide a numerical example if needed. My problem is the following: I am using amelia to input some missing data in a dataset. The problem is that some columns consist of integer numbers only and amelia inputs some real numbers with decimals. Is there a way to tell amelia that cert

Yes, it depends on psych whoich depends on mnormt and all perfectly well declared, henc install.packages() should have done the job for you and installed the dependencies. Probably you did not use it for installing the package. Best, Uwe Ligges On 06.01.2016 19:08, Sarah Goslee wrote: That

Re: [R] HELP - as.numeric changing column data

You may have read in your data incorrectly - a column you expected to be numeric was not recognized as such so it was read in a character and then converted to a 'factor'. FAQ 7.10 tells how to work around the problem https://cran.r-project.org/doc/FAQ/R-FAQ.html#How-do-I-convert-factors-to-numer

Re: [R] HELP - Hausman Test + systemfit

Dear Kateryna The hausman() method for objects of class "systemfit" tests multiple-equation models estimated by 3SLS against multiple-equation models estimated by 2SLS (see documentation, e.g. [1]). It seems to me that this is not the type of Hausman test that you want to conduct. [1] http://www.

Hello, I was under the impression that in a call to gls, if i specify gls(.., cor=AR1(form= ~ 1 | subject)) and suppose there are N subjects, then i would have obtained estimates for N Phi (s) (the AR1 coefficient) - but I only get 1 estimate. I then checked "Linear Mixed-Effects Models Using R

That means you didn't install the dependencies when you installed broom, and now need to install the package mnormt. No big deal, just do what the error message tells you. Sarah On Wed, Jan 6, 2016 at 12:57 PM, James Henson wrote: > Dear R community > > My version is R version 3.2.3. > The pack
