seek(zz,where=NewPosition) returns the OldPosition of connection zz (of the appropriate "pointer", i.e. read or write). Currently, the docs have: > Details: > > `seek' with `where = NA' returns the current byte offset of a > connection (from the beginning), and with a positive `where' > argument the connection is re-positioned (if possible) to

Hi [R-2.6.0, macOSX 10.4.10]. The helppage says that rowSums() and colSums() are equivalent to 'apply' with 'FUN = sum'. But I came across this: > a <- matrix(1:30,5,6) > is.integer(apply(a,1,sum)) [1] TRUE > is.integer(rowSums(a)) [1] FALSE > so rowSums() returns a float. Why is this? -- Robin Han...

...hird argument is "as.integer(length(a))", and urges the user to coerce all the arguments to the correct form (on pain of "hard-to-catch errors" which I now know to be very appropriate, if understated, phrasing). The length() function returns an integer, according to the helppage. So, why does the argument above use as.integer()? -- Robin Hankin Uncertainty Analyst Southampton Oceanography Centre SO14 3ZH tel +44(0)23-8059-7743 initialDOTsurname at soc.soton.ac.uk (edit in obvious way; spam precaution)

...displaying anything at the x,y-coordinates - i want now to display the samplenames at the right x,y-coordinate; i generated a dataframe called lab with the samplenames > lab V1 1 s1 2 s2 3 s3 4 s4 5 s5 6 s6 7 s7 8 s8 9 s9 10 s10 - i??ve studied the "text"-helppage and so i tried the following: text(pca$PC1, pca$PC2, labels=lab) - in the plot there is now c(1,3,4,5,6,7,8,9,10,2) displayed instead of s1-s10 is out there any idea what i'am doing wrong? is there maybe another way of displaying the samplenames at the right x,y-coordinate? greetings from...

Dear list members, I'm a bit confused about the evaluation of expressions using with() or within() versus subset() and transform(). I always teach my students to use with() and within() because of the warning mentioned in the helppages of subset() and transform(). Both functions use nonstandard evaluation and are to be used only interactively. I've never seen that warning on the help page of with() and within(), so I assumed both functions can safely be used in functions and packages. I've now been told that both functi...

Hi Is there a function for computing the standard correlation coefficient (not pearson) in R? Thanks Mick

...way. *** *** Your turn *** What would you like to see in a search capability associated with R? I'd like a web-based facility that could easily produce a package summary table with columns like Package, Count, MaxScore, TotalScore, Date, Title, Version, Author, Maintainer, helpPages, vignette -- possibly with other column(s) for something like "book(s)" or "additional documentation": When I'm searching for something, I often want to know if a package has a vignette, companion book(s) or additional documentation. I believe I can easily add a URL t...

Dear list,   I am looking for an R-only implementation of a Nelder-Mead process that can find local maxima of a spatially distributed variable, e.g. height, on a spatial grid, and outputs the coordinates of the new point during each evaluation. I have found two previous threads about this topic, and was wondering if something similar has been implemented since those messages were posted.   Thank

...of columns and colnames, same number of rows and rownames, similar values which can be in both cases positive and negative numerics. Only difference is that the raw data-sglmarkerfrq is always between 0 and 1, while ln-sglmarkerfrq is because of the ln-transformation also beyond these borders. The helppage of s.multinom() says for the required format of sglmarkerfrq that its rows are "profiles or frequency distributions" - as they are beyond the zero-to-one-broders they are no frequencies, but what is a profile?? Is that causing the error? If so, obviously it's not possible to do a tran...

Hi, I have a large group of jobs, some of them are running on the same directory. All of them in batch mode. What are the best ways to protect from corrupting the results two or more jobs running on the same directory. One, I would think can be to run each job in a separate directory, collect the results and after remove the directories. But I have thousands of jobs that will run in parallel

Hello, i use i.e. the cluster-package and the fanny-object to construct some cluster's and get the membership'S for every "Person" & Cluster ! My finally problem is to match efficient the data and the results's togehter in one table! Until now i use the ODBC-Package and save both in a access-file and copy them together, but i can't be sure that the sorting is the
