similar to: as.numeric in data.frame, but only where it is possible

I'm trying to perform ANCOVAs in R 1.14, on a Mac OS X, but I can't figure out what I am doing wrong. Essentially, I'm testing whether a number of quantitative dental measurements (the response variables in each ANCOVA) show sexual dimorphism (the sexes are the groups) independently of the animal's size (the concomitant variable). I have attached a 13-column matrix as a data

Dear R community members, I think I am asking a very simple question, but I really looked up in the faqs and manuals and found nothing helpful. I am trying to plot a data frame with the following structure (this is just a small extract): glo conc odor line series X1 X2 X3 X4 X5 X6 X7 X8 X9 X10 X11 X12 X13 1 0 AIR LN1 UP -0.488

Hello, I am analyzing some climate time series data using the Mann Kendall package and was wondering if there was a way to calculate the trend using Sen's nonparametric estimator slope in R?

Dear list, Is there a way to do something like the following pseudo-code - without for loop? complexFn <- function(a,b){ ... return(c) } x[i] = complexFn(x[i-1], x[i-2]) I have found "filter" but would like to do something more complicated than multiplication with x[i-1] and x[i-2]. Thanks in advance! gabor

Hi, I wonder if it is possible with the graphics package to overlay one or several plots (barplots, for example) over a map. Data for the map is in a data frame with the latitude and longitude coordinates, and then: > plot(map$long, map$lat, type ="l") produces the map. I want to put each barplot in specific locations on the map, namely at the center of "statistical

Hi, I'm sure this one is very easy.... I am trying to write a function where one of its arguments has two posible (strings) values, defaulting to one of them if none is specified. My problem is that when evaluating the function the following warning is produced: "the condition has length > 1 and only the first element will be used" I've read the help page of if() but I

Hello, In doing a series of non-linear estimations of a function which is a sum of a varying number of sinusoids, I would like to "autogenerate" the arguments needed by nls() depending on that number. For example, when there are two sinusoids: > nls( y ~ mu + A1 * cos(2*pi*f1*x - P1) + A2 * cos(2*pi*f2*x - P2), data = some.xy.data, start = list( mu=some.value0,

Dear list, I would like to plot arrows with different colors according to arrow length, and also (if possible) with head size proportional to arrow length. The idea is to make a quiver-like plot of matlab with wind speed data. So far, I´ve been able to use different colors, but I need to find a more efficient way to recode arrow length intervals into colors. On the contrary, I can't define

Hello, I am loading a DBF file into R via JGR and am having trouble creating small multiple histograms on a date variable. Hist() handles the variable correctly. But I've been unable to work with lattice or ggplot2 despite trying format() and as.POSIXct(). Dates are in the format "2010-05-15" and the grouping variable is categorical. I'd appreciate it if someone would provide an

Hello, I'm a bit new to the world of R so forgive my ignorance. I'm trying to do a zero-inflated negative binomial regression and have received an error message and i'm not sure what it means. I'm running R 2.5.1 on XP. I have just tried a really simple version of the model to see if it would run before I put all the variables in. I have attached all the variables to the

Has anyone any experience of getting the Paypal plug in to work? I''ve set myself up on the Paypal sandbox, I''ve setup my sending and receiving accounts, i''ve got the Paypal button on my view, I can go and make payments ok, but I can''t get the Instant Payment Notification part to work.

Hi, I?m trying to install new package in R (version 2.4.0) under windows vista and i have problems.

Hi all, This is just to announce that I have a FreeBSD x86 machine running the test suite more or less continuously: http://kinoko.c.u-tokyo.ac.jp/~builddonkey/ Of note is that it now runs Dejagnu tests. (Thanks, tonic+co!) I'm also tracking CVS breakage (internally, for now). At some later point, I'll make available more real-time information on "is CVS alive and if not,

Hi all, I''m trying to debug some code in my paypal instant payment notification action. Why can I not access the breakpoint placed inside the action that paypal POSTs to? It just doesn''t find the server, but it works fine when placed inside other actions. I''ve appended the code to the end of this post. Thanks everyone! Tom -- def paypal_ipn notify =

Hello everyone, I am looking for a way to pass off a simple payment to paypal using our own interface. I understand that this requires making full use of Paypal''s API since we won''t be using their shopping cart or anything. I found the article by Pranav Bihari on his site and in the Wiki on using SOAP4R and the paypal WSDL file to interface with paypal web services, but I

Hello everyone I am using paypal-express gem for Payapl payment. I am using reference transaction method to get money from Paypal.

Dear list, Can somebody tell me how to invoke user-defined functions from script files during run-time? Basically I have (almost) one function per script file. I am thinking of something like #include in C++ import in Java/Python use in Perl No, I don't need my functions every time R is started. Neither I am thinking about writing building my functions into packages. I just

I upgraded my Centos 4.7 server last night. Switched from a cheaper 50$ asus motherboard to a Supermicro motherboard. I also, using dd, copied entire 500g SATA seagate drive to new 500g SATA seagate drive so as to have two copies in case something went wrong. Anyway, now I keep getting this error: Nov 21 06:08:33 server kernel: hda: status timeout: status=0xd0 { Busy } Nov 21 06:08:33 server
