Hello All, I am attempting to use the feather.plot function from the plotrix package to graph current velocity data as I have speed and direction. I let "r" be the first 10 rows of current speed data and "theta" be the first 10 rows of directional data in radians. I had tried this with 10 measurements, but keep getting the following error message: >

Hi, I would like to know how R assigns the numeric code to a set of factors in a vector. For example, I have a vector of 5 different factors in a random order, and I want a color-coded plot by factors: rfactor=as.factor(sample(letters[1:5], 50, replace=T)) rfactor [1] c c c d b a b d d a a e e b b e c e e a a b b b a b a e a a b d b b c a b b [39] d c a e c d e d a a a a Levels: a b c d e

Dear List, Following the link below ( http://rgm2.lab.nig.ac.jp/RGM2/func.php?rd_id=plotrix:clock24.plot) I got an interesting polar plots which displayed my data and the time of observation. Thank you very much for providing such details. However, I have two set of data which I wish to display in the same polar plot. I tried using points to add the second data but could not succeed. That is,

Dear All, I am not very into object-oriented programming, but I would like to learn the ropes for some R applications.

I have been trying to visualize times of lowest tides, month by month. I have tide predictions with times either in unix time or a text format, and heights in feet or meters. I had been able to derive the clock times of each prediction. I would now like to graph this data with points showing heights as "r" and times as "theta", from 0000 to 2355. There is a seasonal

Greetings to you all. I have two datasets - Time and magnitude. For a particular location, the magnitude of the parameter varies with time. I wish to obtain a polar coordinate distribution of time (0-24h) and magnitudes so as to visualize how magnitude varies with different times of the day (e.g., morning, midnight hours). I have searched for "polar coordinates in R" but could not get

Dear All, I am trying to generate a circular/radial plot. The script below has a result I am looking for: testlen<-rnorm(24)*2+5 testpos<-0:23+rnorm(24)/4 clock24.plot(testlen,testpos,main="Test Clock24 (lines)",show.grid=FALSE, line.col="green",lwd=3) if(dev.interactive()) par(ask=TRUE) # now do a 'daylight' plot

Kind Experts, Many thanks for your guide. I have tried to figure out something that can help me plot my own data using the examples you referred me to. I copied part of the code as: set.seed(44) N=500 events <- as.POSIXct("2011-01-01", tz="GMT") + days(floor(365*runif(N))) + hours(floor(24*rnorm(N))) + # using rnorm here

I use ggplot2 for all my plotting needs where you can make plots circular with the coord_polar. Maybe this will help you along: http://rstudio-pubs-static.s3.amazonaws.com/3369_998f8b2d788e4a0384ae565c4280aa47.html On Fri, 22 Apr 2016 at 08:31 Ogbos Okike <giftedlife2014 at gmail.com> wrote: > Dear All, > I am trying to generate a circular/radial plot.

Looks like you forgot to load the lubridate package library(lubridate) You are calling functions days(), hours(), minutes(), seconds(), and hour() which all come from that package. ------------------------------------- David L Carlson Department of Anthropology Texas A&M University College Station, TX 77840-4352 -----Original Message----- From: R-help [mailto:r-help-bounces at

Dear All, I am not able to run the random forest with my dataset.. X<- 280 records with satellite data(28 columns) - B1min, b1max, b1std etc.. y<- 280 records with 3 columns - TotBasal Area, Stem density and Volume yref <- y[1:230,] #Keeping 1st 230 records as reference records want to set 0 to y values for records 231 to 280.. yimp <- y[231:280,] #records for which we want

Dear list, I am using the ?clock24.plot command in this excellent package to plot animal activity data. Does anyone know if both symbols and a line can be plotted on the same plot to show both raw data (symbols) and a line (describing a statistical model of the pattern) ? Or if more than one line etc can be plotted? Thanks Paul

Hi Folks, Here is my attempt at a simple polar plot. > pos <- seq(0,360,by=5) > tspk <- rep(c(1,0,1),c(13,47,13)) > require(plotrix) > polar.plot(tspk,pos,rp.type="s",point.symbols=17,point.col="green4") I only see half the symbols, the other half of each symbol is hidden under the circular grid. In fact if I change rp.type="r", I see the

Dear Friends, Yesterday I posed a question to the list concerning the possibility of doing animation examples in R. Here is an example S-Plus (4.5 for Windows ) that I wrote to illustrate my problem. If I try this in R (comment out the graphsheet and guilocator calls) I don't see my results until after the function has iterated through the 100 trials. I would like to plot each iteration.

Hi everyone, I am desperately looking for a method to interpolate strings within an SQL statement as follows: I get a lot of rows out of a database (in my example POSITION_to_ZIPCODE Database with holds records for German ZIP Code <--> Gauss-Krueger Coordinate System ) and want this to be selected and computed individually row by row as follows: library(RODBC) channel <-

I thought about that star graph again, and realized that it would be quite a handy thing for visualizing cyclic data like time or compass direction. Here is a cleaned up (and renamed) version to do a polar plot that starts at the right and goes counterclockwise or a 24 hour clock plot that starts at the top and goes clockwise. There are probably other varieties that would be interesting. Jim

Hello. Is it possible to set specify the font used by legend()? I would like to specify a fixed-width font so that I can line up parts of vertically stacked curve labels. For example, it would be nice if I could align the names, ages, and weights in the following three curve labels: Bob age=7 weight=100 Alexander age=13 weight=150 Susan age=20 weight=130 Is there perhaps a clever

Hello all, Is it possible to change the radii line type in radial plots? I wasn't able to find anything online.

I've wrote some code to simulate a random walk in 2 dimensions on a lattice. Basically I want to add something in to make it plot it point by point so you can see what is going on. Heres my code for the random walk in 2d RW2D<-function(N) { i<-0 xdir<-0 ydir<-0 xpos<-vector() xpos[1]<-xdir ypos<-vector() ypos[1]<-ydir for (i in 1:N-1)
