Hi Kostas, The function vectorField in the plotrix package may do what you want. See the example.

R 1.8.0 on Windows XP Professional. A huge THANK YOU to the R Team for this marvelous software. I am making lattice plots of oceanographic data. The usual layout does not conform to plotting conventions that marine scientists use when depth is the independent variable. Under those conventions, plots are made with the origin at the upper left, depth on the vertical axis (increasing as it

The NOAA National Centers for Coastal Ocean Science is hiring a Computational Ecologist, a statistical/computational ecologist with experience fitting advanced spatial models to marine wildlife survey data (e.g., seabirds and marine mammal transects, fisheries trawl surveys) in R and other statistical languages. This is a full-time, long-term stable contract position. We are looking for an

I am exploring the use of loess for oceanographic applications and would like to plot the locations (longitude and latitude) points where the models (salinity~temperature*longitude*latitude,parametric="temperature") are fitted. Chambers and Hastie(1993) explains the locations are nodes of a k-d tree. but I cannot find anything about accessing this information. It would be useful to

Dear R listers, When using smooth.spline to interpolate data, results are generally good. However, some cases produce totally unreasonable results. The data are values of pressure, temperature, and salinity from a probe that is lowered into the ocean, and the objective is to interpolate temperature and salinity to specified pressures. While smooth.spline provides excellent values at the

Colleagues ---------------------------------- System info: R version rw1022 on NT ESS v. 5.1.18 using emacs ver. 20.4 ---------------------------------- As recommended, I keep separate directories for projects, but also use separate sub-directories for types of data (e.g. different oceanographic instruments) within projects. My problem is that I often need to access the objects and data (not

Hi all, I am a beginner trying to use R to work with large amounts of oceanographic data, and I find that computations can be VERY slow. In particular, computational speed seems to depend strongly on the number and size of the objects that are loaded (when R starts up). The same computations are significantly faster when all but the essential objects are removed. I am running R on a machine

I've been using (and loving) R for quite a while now, but I have to admit that something simple is still stumping me. The question is how I can control the box within which a plot is drawn, in cases where I'm controlling the aspect ratio with the "asp" argument. The problem comes up in pdf() and png() output formats, but also with interactive windows, and so I'll

Colleagues, I am analyzing data collected during oceanographic cruises. We have conducted many cruises over the last decade. On each cruise we visit ~50 stations. At each station (termed EventNum)we lower an instrument that measures depth, temperature, salinity and oxygen every few seconds as it is lowered through the water. Data from all EventNums on all cruises are stacked, generating a data

According to the manpage: UseDNS Specifies whether sshd should look up the remote host name and check that the resolved host name for the remote IP address maps back to the very same IP address. The default is ``yes''. Thing is, while sshd *checks*, this doesn't actually control whether or not the client is allowed to connect, it seems at most to be an option that causes

We have a couple of Asterisk boxes with one being the main system with everyone's voicemail and the other a slave used merely to link a couple of remote phones to the main system using IAX. How can one propagate message waiting indication from the main system to the remote phones? g.

Sorry guys; I got a bit lost about Gene's request on this thread; usually a handle dump like # dh > handles.txt it's all we need to see the relationship between the NBP's device handle and the Service Binding handles. Did you get handles.txt? is it available for download somewhere? >>> Gene, after modifying some of Patrick's code I have been able to get the

Dear R-helpers, I have 4-dimensional atmospheric data (x,y,z,t), which I want to analyse on spatio-temporal diversities. As far as I understand there only exists the possibility to construct time series as two-dimensional matrices (mts). For the moment, I hold it in different objects: 1. a four-dimensional array for the spatial related analyses 2. a two-dimensional mts timeserie, which was

Has anyone on the planet, ever gotten Pirates of the burning sea to run under Wine or cedega?????? I would really really hate to have to reinstall windows even in dual boot.

hello, I''ve already asked via Rails channels on this and have received no response, so I''m asking here in hopes someone has run into something similar. I updated to rails 2.3.3 yesterday, and now all of my specs are failing with the following error: Fixture::FormatError in ''PublishedGallery Methods#thumbnail should delegate to its lead asset'' a YAML error

How can I get the the standard error and confidence interval for the prediction in a multiple regression model using the R command? for a simple regression I used *predict(xc, newdata=data.frame(var1=10.),se=T) where xc is the glm model using binomial and var1 is teh variable. * I can get the upper and lower intervals of the prediction Any help is welcome .

Hello All I have just started dabbling into the world of WINE. I was quite excited to have one of my favourite games installed (Sea Dogs). Before I tell you about the problem, let me tell you my setup. I am using Gentoo Linux on x86 and my wine version is 0.9.8. I installed WINE using "emerge wine" I have XOrg v7 installed.

Dear [R] people, I am looking for a method to test if there are any changes (jump points) in a time series data set or not. If there are, I would like to identify the jump points. All the data is available from the beginning so an offline method could be used. The current data set that I have could be seen as a time series with five almost equally sized segments that stands out to have different
