similar to: Res: Scatterplot Showing All Points

Hello all, I'm trying to graph a scatterplot of a large (5,000 x,y coordinates) of data with the caveat that many of the data points overlap with each other (share the same x AND y coordinates). In using the usual "plot" command, > plot(education, xlab="etc", ylab="etc") it seems that the overlap of points is not shown in the graph. Namely, there are

Hello all, I seem to be having a problem importing a data set from Excel into R. I'm using the "read.table" command to import the data with the following line of code: > newborn<-read.table("newborn edit.csv", header=T, sep=",") where "newborn edit.csv" is the name of the file. Unfortunately, I'm getting back the following error message:

Hello all, I have to run a 2 Sample Confidence Interval on some data; the command for such intervals is "confint(...)", but in the help documentation it says that you need a "fitted model object" in order to run this command. What does that mean? The data is very small, it's: x=c(8,12,10,14,2,0,0) y=c(-6,0,1,2,-3,-4,2) and I want to be able to run a Confidence

Hello all, I was wondering if anyone knew how to construct a multiple line graph on R, where there are 2 (or more) sets of data points plotted against some x axis of data, and you can draw a line on the graph connecting each set of data points. For example: A B C D 0.6566 2.1185 1.2320 5 0.647 2.0865 1.2325 10 0.6532

Hi all We are pretty new to R here and trying to achieve something that we believe is possible but it?s not easy to work out how to do it. We are producing scatterplot matrices for e.g. 10 variables. What we would like to do is superimpose 2D kernel density estimators on top of each plot so that we end up with a scatterplot matrix of 2D kernel density (contour) plots. The kernel density plots

I am running R version 2.15.1 in Windows XP I am having problems with a function I'm trying to create to: 1. subset a data.frame based on function arguments (colname & parmname) 2. rename the PARMVALUE column in the data.frame based on function argument (xvar) 3. generate charts plotvar <- function(parentdf,colname, parmname,xvar,yvar ){ subdf <-

I was able to make a scatterplot but ... 1) what does the "86" mean? The "86" shows up on the graph as well. > scatterplot (Shells/TotalEggs ~ Sector, data = data.to.analyze) [1] "86" 2) Also how do you change the Y axis title? I don't want it to read Shells/TotalEggs, instead I would like it to read Average Hatching Rate (%). 3) What does this error mean?

Hi, I want to draw a scatter plot with 1M and more points and save it as pdf. This makes the pdf file large. So i tried to save the file first as png and than convert it to pdf. This looks OK if printed but if viewed e.g. with acrobat as document figure the quality is bad. Anyone knows a way to reduce the size but keep the quality? /E -- Dipl. bio-chem.

Suppose I have the following data I want to scatterplot: > xy [,1] [,2] [1,] 0 0 [2,] 21 4 I start up a graphics window and fire away: > plot(xy) - but because the graphics window is square, the aspect ratio is wrong. So I add: > plot(xy, asp=1) - now the aspect ratio is correct, but the Y range is about -8 to 11, whereas my data has a Y range of 0

Thanks again for your help. I did indeed solve the problem by plotting the initial graph as type='n', then adding my subset of points using 'points'.

Hi everyone, is there a way/package in R that would allow me to select a group of points from a scatterplot by drawing a circle around them or some such? I can use 'identify' to pick individual points, but that gets tedious if one has more than 10-20 spots. I can easily select spots within a rectangle defined by picking points using identify... but a simple rectangle sometimes will

Command I am using for the plot: plot(Raw[][Plate==101]~well[][Plate==101], xlab="Well", ylab="Raw", main="Plate 101") I only want to label points on the graph where well equals B13, G13, K14 and N14 with the name of the well. Thank you for your help. -- View this message in context:

Dear useRs, I'm having trouble with what is likely a very simple issue with a simple graph. I have data in the format pasted below - total from which this is a subset is > 3 million rows. I'm plotting "Window" on the x axis, and either of the other two columns on the y axis. In both the second and third columns, the values are in a range from 0 to 1. I want to be able to plot

Hello, I am new to R and would like to know how to label data points in the matrices of scatterplots made by the pairs() command. To be more specific, I want to assign a number to each data point, instead of the small circumference that appears as a data point. If anyone here knows if its possible to do this with R, I would greatly appreciate your help. Thank you, Mauricio Esguerra PhD

In a plot on an X11 device, I'd like to mark a few points with a large thin "crosshairs". By "mark" I mean: draw the crosshair on the plot. The two unsatisfactory methods that I have are: METHOD 1: points( x, y, pch="+" ,cex=2) METHOD 2: line(xa, xb, y0, y0) line(x0, x0, ya, yb) Method #1 produces a crosshair with fat lines. It is not possible
