I have two vectors min 0.2, 0.3, 0.6, 0.1 max 0.4,0.5,0.7,0.4 Is there a way to combine these two vector so that the values will be taken from the vectors alternating so that I will get a new minmaxminmaxminmax-vector? minmax 0.2,0.4,0.3,0.5,0.6,0.7,0.1,0.4 Any help is much appreciated -- View this message in context:

If I have a data frame where a species occupies several rows with different phases such as (both col's ar factors): species,phase Populus tremula,1 Populus tremula,2 Populus tremula,3 Calluna vulgaris,1 Calluna vulgaris,2 Betula alba,1 Betula alba,2 Betula alba,3 Primula veris,1 Primula veris,2 and another df where each species only have one row: species,growth_form Populus tremula,tree Acer

I have a file that reads like this: Species,Year,Julian_day Alnus_glutinosa, 1873, 123 Sorbus_aucuparia, 1873, 122 ....(more species...) Alnus_glutinosa, 1874, 134 Sorbus_aucuparia, 1874, 143 ....(more species and years) Is there a way to plot this as julian day over years so that each species get a different color? Also is it possible to convert this data into the format: Alnus_glutinosa,

I was just thinking of a way to present data and if it is possible in R. I have a data frame that looks as follows (this is just mockup data). df location,"species1","species2","species3","species4","species5" "loc1",0.44,0.28,0.37,-0.24,0.41 "loc2",0.54,0.62,0.34,0.52,0.71 "loc3",-0.33,0.75,-0.34,0.48,0.61 location

In response to those who asked for a better explanation of what the Vilno software does, here's a simple example that gives some idea of what it does. LABRESULTS is a dataset with multiple rows per patient , with lab sodium measurements. It has columns: PATIENT_ID, VISIT_NUM, and SODIUM. DEMO is a dataset with one row per patient, with demographic data. It has columns: PATIENT_ID, GENDER.

I'd like to do some plots of historical event data on a reverse log scale, started, say at the year 2000 and going backwards in time, with tick marks spaced according to log(2000-year). For example, see: http://euclid.psych.yorku.ca/SCS/Gallery/images/log-timeline.gif As an example, I'd like to create a density plot of such data with the horizontal axis reverse-logged, a

Hello, New to this forum so I hope the content is appropriate... I was building a some code to maniputlate some data. Given the bulk of it (the csv is about a GB), I opted to use a database. The setup, which may be part of the issue is that the SQL is one remote machine (call it 'A'), the disk that contains the data is on some other remote drive - call it 'B' and the server on

Hello Suppose I have a matrix mat=(1:16,2) [,1] [,2] [,3] [,4] [1,] 1 5 9 13 [2,] 2 6 10 14 [3,] 3 7 11 15 [4,] 4 8 12 16 I just want to use the "apply" function to the matrix partially there is a vector end=c(2,3,1,3) #sum the 1st 2 numbers of the 1st column #sum the 1st 3 numbers of the 2nd column #sum the 1st number of the 3rd column

I have a two-column table as follows where age is in the 1st column and the number of individuals is in the 2nd. age;no 1;21 2;31 3;9 4;12 5;6 Can I use mean() and sd() to calculate the mean and standard deviation from this or do I have to manually multiplicate 21*1+31*2 etc. / N?

Hi, I am trying to create Bid/Ask for each second from a high volume stock and the only way I have been able to solve this is using loops to create the target matrix from the source tick data matrix. Looping is too slow and not practical to use on multiple stocks. For example: Bids Matrix (a real one is 400,000++ length): Bid Time 10.03 11:05:03.124 10.04 11:05:03.348 10.05

I am trying to figure out how to use rgl package for animation. It appears that this is done using the play3d() function. Below I have some sample code that plots a 3D path and puts a sphere at the point farthest from the origin (which in this case also appears to be at the end of the path). What I would like to do is animate the movement of another sphere along the length of the path

Hello. I'm writing some simple text using sweave, and faced a strange problem with eps files produced for my plots (one example attached). Individual eps files are interpreted by ghostscript just fine, and show up without errors. But once I try to include them into main LaTeX/Sweave document (using regular \includegraphics, produced by Sweave), ghostscript gives me this error on those files:

I was just wondering if anyone knows what could be the problem with my exporting of plots. Below is the error messages I get when trying to export my plots (all error messages at the same time). I do get a file produced which works but I don't know why these messages appear. Doesn't matter if it is a pdf or a png or any other format I export to. Also, when exporting to png I get

Hi, I have some questions about running multiple tinc deamons. The docs say you can do it to support separate VPNs, but I don't see any examples. I have been running a single tinc vpn for months with no problems, now I'm trying to add a second separate vpn. I'm running the static tinc version 1.0pre7 (built Apr 9 2002 14:00:34, protocol 14) on Debian potato. I did not want to go
