Hi All, would appreciate an answer on this if you have a moment; Is there a function (before I try and write it !) that allows the input of a covariance or correlation matrix to calculate PCA, rather than the actual data as in princomp() Regards Glenn [[alternative HTML version deleted]]

For a list say; list1<-{1,2,3,4,5,2,1} How do I remove the duplicates please? My real list is 20,000 obs long of dates with many duplicates Regards Glenn [[alternative HTML version deleted]]

Hi All, I have a small dataframe [dates, values) I am plotting with plot(df,type=²l²) And the date date covers a year. The graph only have marks at Œ2008¹ and Œ2009¹. How do I get the months labeled at the bottom please Thanks as always Glenn [[alternative HTML version deleted]]

Hi All, some help on this would be appreciated; Understood combinations(7,4) returns all the possible 4 part combinations out of 7. Is is possible to substitute the ³7² for a list of stuff you would like to see the mix of; c(³a²,...,²g²) say ? Thanks Glenn [[alternative HTML version deleted]]

Dear All; Is it possible to create a list of lists (I am sure it is) along these lines; I have a dataframe data02 that holds a lot of information, and the first column is ³date² I have a list of dates in; data03<-c(date1,.....,daten) And would like to create a list; data04 <- subset(data02, date == data03[1,]) Ie. data04 holds the data from data02 that matches a date in data03 How do

Help with this much appreciated I have a large dataframe that I would like to subset where the constraint Test1 <- subset(df, date == uniques[[1]]), where uniques is a list of dates that must be matched to create Test1. I would like to perform an operation on Test1 that results in a single column of data. So far so good. How do loop through all values in the uniques list (say

Very simple questions if anyone can help: (1) what is the value in saving workspaces, which is offered at every close? I thought it might save the set up of the GUI but I cant work out what it does ­ I run a script that loads the packages I need at the start of every session. (2) mathematica has a term (%) that when typed means the last returned value, so > % + 1 say would return the last

Newbie question sorry (have tried the help pages I promise) I have a dataframe (date,stockprice) say and looking how I might get the return of: dataframe (difference in days, change in stock price) using sapply - I require a very simple function and don't really want to go down the zoo and quant mod route Regards glenn [[alternative HTML version deleted]]

Very quick newbie question sorry; How do I standardize a list of data please (other than do the calculation of course). Is there a quick way please ? glenn [[alternative HTML version deleted]]

Hi there, Could someone help me with the following programming problem..? I have written a function that works for my intended purpose, but it is quite closely tied to a particular dataframe and the names of the variables in this dataframe. However, I'd like to use the same function for different dataframes and variables. My problem is that I'm not quite sure how to tell my function in

I'm using RC15 on Solaris 9. The wiki indicates that when a dovecot-shared file exists, "Dovecot uses the same permissions and GID when it creates index files, dovecot-uidlist file, new mail files, etc." In my case, Dovecot *is* creating new index files based on dovecot-shared, but dovecot-uidlist and individual message files don't completely match the permissions/group

Initially when I posted my access problems to print$ I was using the new registry based smb.conf I had my whole configuration in the registry. Now I move my printers and print$ back to the text based smb.conf and I copied the standard ubuntu debian [printers] and [print$] out of the original ubuntu package smb.conf and the only modification that I made was under the [print$] I change read only to

Another Newbie Question sorry: I am trying to apply a function a dataframe and could use some help: Assuming, dim(df) = (10,2) say, I would like to apply a function that looks at each row in turn and returns a list (dim =(10,1)) using the columns as inputs to the function, but with no INDEX stuff that the by() function refers to. For a simple function x+y I know in Mathematica it would be

Hi all, Since three month ago I started working with R professionally, I never did it before, so I am such a newbie. I am having some problems using the 'debug' package. I love this package, but most of the times I wanna use it it just fails :P When typing at prompt 'mtrace(myfunct)' most of the times I get the following error: "Error in x[[i]] : subscript out of

Does anyone have any hints or suggestions on getting some JetDirect-based printers set up for bidirectional printing in Samba? We're using LPRng 3.8.0, ifhp 3.4.7, and samba 2.2.2 From the LPRng standpoint, the printers seem to be set up for bidirectional communication fine.. but how do we get Samba to allow bidirectional communication? Thanks in advance! Glenn --- Glenn E. Sieb,

Has there been any update on R's handling large integers greater than 10^9 (between 10^9 and 4x10^9) ? as.integer() in R 2.9.2 lists this as a restriction but doesnt list the actual limit or cause, nor if anyone was looking at fixing it.
