similar to: using save() to work with objects that exceed memory capacity

Dear Sir: When I try to save large and very complex recursive objects with some components containing models (such as the output from arima or lm ), the resulting file sizes increase by 4 meg per save. example directory: amex 8 meg argentina 12 meg australia 16 meg ... Moreover, I am unable to read these file objects back into R. I note that readBin and writeBin

Hi, I cannot seem to find out how to pass in a value to a partial. Can anyone help me? What I am doing(in the code below) is calling a function in my controller called setobject. This function just redraws the partial. I want to be able to change the value @objectname, redraw my partial and have it be able to use that value. The first the page is drawn it works, but when i call setobject it

I am still struggling to map a character string to an object name and vice versa in R. I thought the as.name() function might work, but observe the following behaviour ... > attach(warpbreaks) > levels(tension) [1] "L" "M" "H" > levels(as.name("tension")) NULL > objectname<-as.name("tension") > objectname tension >

Is there anyway I can convert a vectors objectname to a string to be used in fx: Monkey<-c(0,0,0,1,1,1) Wax<-c(1,0,1,0,1,0) f<-function(x,y){ table(x,y) } f(Monkey,Wax) so that the printout is not y x 0 1 0 1 2 1 2 1 but Wax Monkey 0 1 0 1 2 1 2 1 -- View this message in context:

Dear List, I have a series of nested loops with the structure shown below, and I am struggling to figure out how to divert output to folders created with dir.create() within the loops. What I need is for the output to end up as topNameK/subNameL/objNameM.pdf; what I get instead is a series of directories topNameK/, directories subNameL/, and files objNameM.pdf, all in the working directory. Any

Does anyone know how to do a fry plot in R? I have 600-800 points per image, and I really don't want to attempt that manually. Thank you! Cassie [[alternative HTML version deleted]]

Hello All, When I use bw.SJ (based on Sheather & Jones, 1991) in R to estimate the bandwidth for a highly skewed data, I get the following message: "sample is too sparse to find TD". I played around with the parameters such as no. of bins (nb), lower, upper (range over which to minimize) to no avail. My sample size is 50,000. Can anyone tell me what this means and of some

Hello I have a matlab MAT file that contains one single variable: a. The structure of a is as follows: a.river1.flow (flow values) a.river1.date_flow (date) a.river1.precip (precipitation values) a.river1.date_precip a.river2.flow a.river2.date_flow a.river2.precip a.river2.date_precip I have used readMat to load the variable a in R, however I have no idea how readMat translates a. I managed

Dear R gurus, I have a function "goftests" that receives the following arguments: * a vector "x" of data values; * a distribution name "dist"; * the dots list ("...") containing a list a parameters to pass to CDF function; and calls several goodness-of-fit tests on the given data values against the given distribution. That is: ##### BEGIN CODE SNIP #####

Using R 2.4, the following fails: setClass("testc", representation(a="ANY")) makeC <- function(myarg) new("testc", a=myarg) makeC() -> Error in initialize(value, ...) : argument "myarg" is missing, with no default On the other hand, this is OK: f <- function(a) g(b=a) g <- function(b) if(missing(b)) "missing" else "valid

Hello, I am using the lmomco package (lmom.ub and pargev) to compute the GEV parameters (location, scale, and shape), which are used to estimate return values. I was wondering how/if I can calculate upper and lower confidence (CI_u, CI_l) intervals for each return frequency using the GEV parameters to fill-in the table below? Xi (location) = 35.396 Alpha (scale) = 1.726 Kappa (shape) =

Hi, I need to run a PCoA (PCO) for a data set wich has both positive and negative values for variables. I  could not find any distancecoefficient other than euclidean distace running for the data set. Are there any other coefficient works with negtive values.Also I cannot get summary out put (the eigen values) for PCO as for PCA.   Thanks. Dilshan [[alternative HTML version deleted]]

Thanks to everyone who responded to my first set of questions. Not only did I get my questions answered but I improved my code and learned a couple new things. I think I prefer the mailing list over IRC... easier to follow :-) I have some more questions if you don''t mind. Some are Rails related and some are Ruby related. 1) This is concerning displaying error messages. I am assuming

Hola a todos, Estoy utilizando la libreria e1071 para clasificar unos datos. Me gustaría poder guardar los modelos en el disco duro y no en memoria de R. He visto que hay una función: save : que guarda el modelo en memoria y load: que carga ese modelo Ejemplo: #saving the best model save(calibrate.rf.model1, file=''bestmodel.rda'') #loading the best model

Hello everyone I hope Im not bothering you all again. I have just begun to use R and so Im not yet familiarized with it.. I ve got an assignment which consists in calculating the area of a circle given a certain radius and center using the monte carlo method, which means that I have to plot a circle given its parameters. Limit the area inside it...with as many sample points as possible...and

So a little background, in my domain we have 2 domain controllers, the main (A Windows Server 2008 R2), and a secondary that is was recently migrated from Server 2003 R2 to Samba. Both domain controllers are offsite so we use OpenVpn to connect them, dns is set to the samba domain controller then the Windows server, this is due that the samba domain controller is up 24/7 while the Windows is only

I use the ff-package for large data and have good success in session. To ensure my data is available for the next R session, I save my workspace and use the /ffsave/ command to archive my large data objects. Syntax is simple: > ffsave(file="~/path/archiveName", list="objectName") when I have multiple files to save, the list is expanded using c(). When I start a new R
