similar to: drawing a circle using symbols

Hi, I am trying to draw a dotted circle by using symbols command: symbols(0, 0, circles = 1, inches = FALSE, fg = 'gray', lty=2) But it gives me a solid line. I was just wondering whether am I making a mistake? Ved [[alternative HTML version deleted]]

Hi there. I have been plotting some circles using 'symbols', with radii representing my data, but the radii looked incorrect. It seems to happen with a single circle too: Symbols ( 0, 0, circles = 40, xlim = c(-40, 40), ylim= c(-40, 40)) If I put a ruler up to my monitor (technology!) to compare the radius with the axes, the circle isn't radius 40; it is closer to 15... I

move or copy the directories mass, nnet and class to the library directory - then execute link.html.help() Now execute library(MASS) and data(petrol) Should work. "Troels Ring"

Dear friends - I'm using Tinn-R in Windows and find it OK. My son is running MacOS and is just starting using R and I know nothing about MacOS and R but we seem to have difficulties in finding something similar to Tinn for MaC. What are your suggestions? Thanks a lot! Troels Ring, MD Aalborg, Denmark

Dear friends. I have trobpe with path. Below I have tried to paste a path and file name but it will not work > path <- "D:/rw0641/own/own/procedures/GFR_TIME" > path [1] "D:/rw0641/own/own/procedures/GFR_TIME" > path1 <- paste(path,"gfr.txt",sep="/") > path1 [1] "D:/rw0641/own/own/procedures/GFR_TIME/gfr.txt" -- this is good

Dear Friends, I'm using winXP and R 1.7.1 and plotting some data using dates on the x-axis, and wanted to use identify to show some points but was told by identify that the x and y vectors producing a fine graph with 84 points were not equal in length. Below are the Dato for date - and length(Dato) finds 9 but str finds 84 as known. Will identify not work in this context ? Best wishes

Hi, I'm using windows xp and R 2.8.0 - I wonder what is the command to put in a script that has the same effect as when in a plot you choose menu "History" and "Recording".

I hope you will forgive me this simple question on titration. I'm trying to find very small values from the algorithm below, which I believe is correctly formatted, and the constants are also correct. When SID goes over ATOT, fitted vales are much too low compared to the literature. I guess I must be using optimize in a wrong way but cannot find out how to improve it. I'm on windows, R

Hi. I need to draw a circle whit center (a,b) and radio r. So I use the R code below a<-1.975 # valore x del centro b<-1.215 # valores y del centro r<-1.46 # radio x1<-seq(a-r,a+r,by=0.01); #los valores de x yp<-sqrt(r^2-(x1-a)^2)+b; # los valores y a partir de la ra??z positiva yn<-(-1)*sqrt(r^2-(x1-a)^2)+b; # los valores y a partir de la ra??z negativa x<-c(x1,x1);

Dear friends - below is a subset of a much larger material showing two ways of generating two "lines". The intention is to have the colour reflect a variable, pH, but the legend is disturbed. The little part marked "3" above the colour scale is unwelcome. Why did it appear? How could I avoid it? I'm on Windows 7, R version 3.4.1 (2017-06-30) -- "Single

Hello, I am not able to plot a circle of a given radius using symbols(). In the example below, the circle appears too large: plot(0, 0, xlim = c(-1, 1), ylim = c(-1, 1)) symbols(0, 0, circles = 1, inches = FALSE, add = TRUE) What's happening? Ery

Hi all, I'm trying to use symbols() to draw a circle of a given radius at a given position onto a filled.contour() plot. The commands I issue are: > filled.contour(y,x,z,levels=seq > (0.02,1.0,len=50),color.palette=colorRampPalette(c > ("blue","yellow","red")),title=title(main="",xlab="",ylab="")) >

Dear friends - I hope you will accept a naive question on lm: R version 3.4.1, Windows 10 I have 204 "baskets" of three types corresponding to factor F, each of size from 2 to 33 containing measurements, and need to know if the standard deviation on the measurements in each basket,sdd, is different across types, F. Plotting the observed sdd versus the sizes from 2 to 33, called

Dear friends - I have a data.frame with "," instead of "." and found the discussion http://r.789695.n4.nabble.com/How-to-replace-all-commas-with-semicolon-in-a-string-tt4721187.html#a4721192 so copying the code of Ulrik(I hope:-)) I tried (making some data) AX <-

Dear friends - I'm on winXP, R 2.71 - I have with some help dveloped this multivariate normal model, which gives very plausible results in WinBUGS even without any initial values specified. However, when I then try to run the same model via the bugs function in R2WinBUGS with inits specified as inits=NULL the program stops in a dead end. So I have tried to make inits for the bugs function

Dear friends, I found the thread on this subject this summer but wonder whether it has been taken any further. I have an important medical problem where X is computed from a three independent and complicated measurements (exchangeable sodium and potassium and total body water - i.e. X = (Nae+Ke)/TBW ) and Y is serum sodium concentration (all data in Edelman, JCI 1958). I have the individual

Dear list, I am trying to program semi-random movement within a circle, with no particles leaving the circle. I would like them to bounce back when they come to close to the wall, but I don't seem to be able to get this right. Would somebody kindly give me a hint ? This is my code so far, the particle starts at some point and moves towards the wall, but I don't get the "bouncing

Dear friends. Please see the program below and answer if it does simulate a population of 1.000.000 families, each with at max 20000 children (typical in Denmark, you know), constructed such that each family stops having children when more boys than girls are present ? Equal numbers of boys and girls are got in the population, according to the simulation, is that obvious ? ND <- NP <-
