Full_Name: Mike Ulrich Version: 2.9 OS: Mac OSX Submission from: (NULL) (69.169.178.34) The help documentation for loadings() lists more then one parameter. The function call only expects one parameter. The digits, cutoff, and sort parameters are not used in the function. ## S3 method for class 'loadings': print(x, digits = 3, cutoff = 0.1, sort = FALSE, ...) ## S3 method for class

Dear Users, I ran factor analysis using R and SAS. However, I had different outputs from R and SAS. Why they provide different outputs? Especially, the factor loadings are different. I did real dataset(n=264), however, I had an extremely different from R and SAS. Why this things happened? Which software is correct on? Thanks in advance, - TY #R code with example data # A little

Dear list members, I apologize for putting this (probably) very basic question on the mailing list. I have scanned through the R website (using search) but did not found an answer. (code included below) A factor matrix is simply extracted (which can then subsequently be exported using write.table) by FACT$loadings[1:6,]. I would also like to specifically extract and export

Hi, I wonder why factor scores produced by factanal are correlated, and I'd appreciate any hints from people that may help me to get a deeper understanding why that's the case. By the way: I'm a psychologist used to SPSS, so that question my sound a little silly to your ears. Here's my minimal example: *********************************************** v1 <-

Dear all, The 'make check' step fails for the pacakge mva on IBM AIX. The tail of the Rout log file looks like: > for(factors in 2:4) print(update(Harman23.FA, factors = factors)) Call: factanal(factors = factors, covmat = Harman23.cor) Uniquenesses: height arm.span forearm lower.leg weight 0.170 0.107 0.166

Hi there, Does anyone know how to explicitly refer to the p-value of thet test that the chosen number of factors is significant in a factor analysis. It's not in the list of values for the factanal command output yet it is printed out with the results. Thanks in advance. Wayne Dr Wayne R.

Dear list members, Could any expert on factor analysis be so kind to explain how to calculate AIC on the output of factanal. Do I calculate AIC wrong or is factanal$criteria["objective"] not a negative log-likelihood? Best regards Jens Oehlschl?gel The AIC calculated using summary.factanal below don't appear correct to me: n items factors total.df rest.df model.df

Hi R users, I need some help in the followings: I'm doing factor analysis and I need to extract the loading values and the Proportion Var and Cumulative Var values one by one. Here is what I am doing: > fact <- factanal(na.omit(gnome_freq_r2),factors=5); > fact$loadings Loadings: Factor1 Factor2 Factor3 Factor4 Factor5 b1freqr2 0.246 0.486 0.145

--=-hiYzUeWcRJ/+kx41aPIZ Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 8bit Hi, on March 10 I filed a wishlist bug report asking for the inclusion of some changes to factanal() and the associated print method. The changes were originally proposed by John Fox in 2005; they make print.factanal() display factor correlations if factanal() is called with rotation =

Hi, Does anyone know if R has the functionality to calculate a simple moving average. I cant seem to find it in the help menu. thanks, Wayne Dr Wayne R.

Hi there fellow R-users, Does anyone know if there exists a package for associated rules data mining (market basket analysis) in R. I have tried searching CRAN but with no luck.

Hi there fellow R-users, Can anyone tell me if there exits an R package that deals with serial correlation in the residuals of an lm model. Perhaps, using the Cochrane Orcutt or Praise Wilson methods? Thanks, Wayne Dr Wayne R.

Hi there fellow R-users, I'm stuck on this seemingly trivial problem. All I want to coerce a character string into a command. For example: x<-rnorm(20) y<-rnorm(20) str<-"lm(y~x)" I want to evaluate the "str" command. I have tried eval(as.expression(str)) But it doesn't seem to work. I am aware of the call command, but for reasons I won't go

Hello there fellow R-users, I am using the RODBC functionality to query a database. I am trying to read in a columns of strings which have a character field lengths greater than 255. The data.frame that I recieve back from the RODBC query only contains the first 255 characters (the rest having been truncated). Any help on how to solve this problem would be greatly appreciated.

Hello All, Does anyone out there know a way to decompose time series objects with missing values. A simple "na.omit" will not work since it does not preserve the time differences between succesive observations. Thanks in advance, Wayne Dr Wayne R.
