Hello R-helpers! I have a question concerning extracting sequence information from a vector. I have a vector (representing the bins of a time series where the frequency of occurrences is greater than some threshold) where I would like to extract the min, median and max of each group of consecutive numbers. For Example: tmp <- c(24,25,29,35,36,37,38,39,40,41,42,43,44,45,46,47,68,69,70,71) I

Hello R-users! I have a style question. I know that for loops are somewhat frowned upon in R, and I was trying to figure out a nice way to do something without using loops, but figured that i could get it done quickly using them. I am now looking to see what kind of tricks I can use to make this code a bit more aesthetically appealing to other R users (and learn something about R along the

R-masters, I have a problem that I have been working on for a while and it seems that there may be a simple solution that I have yet to figure out, so I thought that I would venture to post to the help list. Let's say there was a data.frame with three vectors, two that are factors identifying the data, and one that holds the frequency of occurrence (the events are binary, yes or no). I

Hello all, This is something that I am sure has a really suave solution in R, but I can't quite figure out the best (or even a basic) way to do it. I have a simple linear regression that is fit with lm for which I would like to estimate the x intercept with some measure of error around it (confidence interval). In biology, there is the concept of a developmental zero - a temperature under

Hello R help-ers, I have a basic question, but I have been playing with it for a while and haven't quite gotten a hang of how to get it working. I want to perform multiple one-way ANOVAs on subsets of data and am not sure how to do it in an automated way. I am thinking of doing something similar to 'aggregate' but I would like to collect all of the ANOVA results in a way in which I

Hey there, I apologize if this is an irritatingly simple question ... I'm a new user. I can't understand why R flips the sign of all data values when reading in external text files (tab delimited or csv) with the read.delim or read.csv functions. The signs of data values also seem to be flipped after assigning a new data.frame from within R (xnew <-- edit(data.frame()). What am

A recent article in the earth science literature cited below and available at http://geography.uoregon.edu/datagraphics/EOS/ points out that rainbow color schemes and mixtures of green and yellow can be troublesome for people with color-deficient vision. The authors propose alternative schemes that can be viewed and downloaded in RGB, HSV, CMYK, and RGB256 formats from

Hi, I have Samba 3.0.14a + OpenLDAP 2.2.24 installed on Solaris 8 as a PDC for serving files only (no profiles, no printing). Performance of network browsing is slow in Windows 2000 and XP, taking 10-15 seconds to open and display the contents of a folder. The same browsing activity from a Mac works fine with no unacceptable delays. I'm trying to sell Samba here, but these delays are

Hi All, I finally signed up for the list after years of using Samba successfully - a testament to the quality of Samba. Yet now I have a problem with the point-and-print functionality. I am able to authenticate against my server (Solaris 8, Samba 3.0.7, OpenLDAP 2.1.25) as user 'chuck' in my LDAP directory and browse the shares, but when I right-click on the printer and select

Hi Collective users of Samba, (does has a nice ring to it eh?) Recently I found a my samba server being infected by win32 viruses. Though it does not affect the server in any way, I do find them to be an annoyance. I understand also that I can perform "veto" of files like *.exe in smb.conf but find that to be a wee bit restrictive. There are some users who stores valid executables in

We recently upgraded from Dovecot 1.2.4 to 1.2.6 (with the sieve patches of course). Everything has been running quite well since the upgrade. The occasional issue with assert-crashing when expunging has gone away. However, one of our users seems to have triggered a new issue. She's been the only one to see it, but whenever she logs in, her imap process segfaults immediately. It appears that

Hi, I want to automate a set of scripts that spit out data that are later used by R to plot graphs. However, I need to get into R's environment now and then use my R script using the source command. Is there a way to run the R script from the unix prompt ?. Thanks, Krishnan. ----------------------------------------------------------- Sivaramakrishna Iyer Krishnan (Anand) Research Assistant

I've created a perspective plot using 'persp' in the graphics package. I'd like to add a second plane of z values to the existing plot, but I cannot seem to do this using 'persp'. Is there an analogue to 'lines' or 'points' for perspectives? Corey. corey.bradshaw at cdu.edu.au

Hello colleagues, I am attempting to determine the nonlinear least-squares estimates of the nonlinear model parameters using nls. I have come across a common problem that R users have reported when I attempt to fit a particular 3-parameter nonlinear function to my dataset: Error in nls(r ~ tlm(a, N.fix, k, theta), data = tlm.data, start = list(a = a.st, : step factor 0.000488281

Dear colleagues, I've been running some principal components analyses, which generate tables of loadings that I'm interested in looking at. print(f1$rot$load,cutoff=.4) is what I use, and it gives me what I want. However, I'm now interested in comparing these loadings across a few data sets. In other words, I would like R to match the loadings on rownames() and display them next

Dear Colleagues, I've been searching for a post or article or something which explains why having na.rm=FALSE or na.action=na.fail as the default is a better choice than TRUE or na.omit. I understand the basic argument: it does not make sense to average a nonexistance into an aggregate, and removing them implicitly leads to accidental pairwise deletion in some cases, and sum(x) /

Hi, I am working on establishing a Samba+LDAP server with management by the smbldap tools from idealx. Versions are Samba 3.0.14a, OpenLDAP 2.2.24, smbldap tools 0.8.8 all on Solaris 8. I'm thinking I have a problem with my perl (perhaps), version 5.8.5, as I keep getting "Broken pipe" messages when using smbldap-populate, smbldap-groupadd, etc. Google produced no useful

Dear colleagues, Has anybody any experience using the sem package to fit structural equation models using a fitting function other than ML? I have heard tell that OLS may provide better estimates when using standardized matrices generated from small sample sizes, so I was interested in comparing the two for a few models. However, ML appears to be hard-coded into the source for sem...but maybe
