Hello everyone, I would like to know if there is any function to calculate the mode value, or I have to build one to do it. Thanks so much Carlos

Hello all, First of all, thanks for your examples to calculate the mode value. But now my problem is the next: I have a?factor and I'm trying to convert it to number with as.numeric(x) but when I see the number it's different, I mean if I have: b<-1,042 d<-as.numeric(b) then when I show d, it appears 432 and I want to work with 1,042 because then I want to calculate the median of

Hi, how can I create a rainbow gradient in R? For example, let's say I have a plot of y = x...and I want the plot to go from red -> orange -> yellow -> green -> blue -> etc. Right now, I know how to do something like go from red to blue, using the plotrix library: library(plotrix) redToBlue <-

Hello, I would like to know what can I do if I use strplit with a string and I want to use the middle left,I mean I have this: strsplit("bA531F16-rep","\\-") [[1]] [1] "bA531F16" "rep" I would like to work just with bA531F16 in another variable, what could I do?, Thank you --------------------------------- Sé un Mejor Amante

Hi, Is there a way to use par to change the colours of the axes lines (not the labels)? I've done this: par(bg = "black") plot(x, y, col = "yellow", pch = 16) but I have to use axes = F within the plot command, and then use axis (1, col = "yellow") axis (2, col = "yellow") and so on for axes 3 & 4. This does not help since the new axes are not

Using Rgraphviz, I draw the undirected graph with vertices A,B,C and D and edges A:B, B:C, C:D, D:A, A:C. I want the vertices A and B to be red and C and D to be blue. The problem is the following: I want the edges A:B and B:C to be green and the edges C:D and C:A to be yellow, while the edge A:C can have the default colour black. I assume that I have to specify this using the edgeAttrs-argument

Dear all, This seems like a simple problem but i've searched the help files and tried various options but failed, so apologies in advance for asking what i'm sure is an easy thing to do! In short, I have displayed behavioural data using the TraMineR package such that there is a colour change between the transition of behaviours, however, all the methods that i have used thus far have

I'm fairly new to the silhouette functionality in the cluster package, so apologize if I'm asking something naive. If I run the 'agnes(ruspini)' example from the silhouette section of the cluster package vignette, and assign colours to clusters, two clusters have what appear to be incorrect colours in the silhouette plot. library(cluster) data(ruspini) ar<- agnes(ruspini)

Hi! I am new to R just 3 days in it and i apologize if my questions seem very trivial and consumed your valuable time. I am coding in perl and i stumbled upon R regarding plotting good statistical graphs. I tried the kmean clustering for a large matrix ,say > 150 * 150 . I tried the example code given in the tutorial to perform 2d plot # i ranges from 2 to 10 cl <- kmeans(x, i, 20)

Are there any R functions for creating palettes for three-way data? For example, election maps for three parties where pure red, blue, and green show 100% for the Red, Blue, and Green parties respectively, magenta shows a 50-50 Red-Blue split with 0 for the Greens, cyan a 50-50 Blue/Green split with no Red votes and so on, with grey, black or white at a 1/3,1/3,1/3 split vote. I've spent a

Hi. I want to use image() with colours that are indexed by two variables. Indexing by one variable is easy: library(colorspace) x <- seq(from=0, to=1,len=30) z <- outer(x,1i*x,"+") image(Re(z),col=hcl(seq(from=0,to=100,len=15),c=100)) OK, so far so good. Now, I want the colour to be a more complicated function of z, in which both the hue and luminance change (thus the colours

Inspired by colouring the dots of box-whisker plots I am trying to also fill the boxes (rectangles) with different colours. This seems not to work as I expected. Looking at the help page of panel.bwplot it says: 'fill - color to fill the boxplot'. Obviously it is only intended to fill all boxes with only one colour? Nevertheless the following example shows, that 'fill' from

Hi all, I've just could test your suggestions on using dataedit... entries now, and indeed they work... partially. See, please, the next screenshot: https://ibb.co/Dkn2pVs dataedituser modifies the red borders dataedittext the yellow text dataeditfg... I do not know, specified to green the output of View(mtcars) does not change from that of the screenshot dataeditbg is the (almost) black

Hi all, As the email subject tells, I write to ask if there is the chance to customize the colours (and in particular the background) of the `View` output window. In the View help, it is told that: On Windows, the initial size of the data viewer window is taken from the default dimensions of a pager (see Rconsole), but adjusted downwards to show a whole number of rows and columns. So if

Dear R-help, Could any of you direct me to a function for plotting a grid of colours, directly specified by a matrix of hex colour codes? In other words I'm looking for a heatmap() or image()-like function to which I can specify the colour of each grid location directly, rather than providing a numerical matrix and a 1D-colour scale (heatmap, image, levelplots,NeatMap...). I'm surprised

Hi, I have reconstructed ancestral character states on a phylogeny using MuSSE in the diversitree package and plotted the character state probabilities as pie charts on the nodes. I would, however, like to colour the character states of my extant species, i.e. the tip labels, the same colours as my pie charts, such that all species in state 1 are e.g. blue, species in state 2 red and species in

I have a strange issue with Brother MFC-5440CN printer. When I print from Linux/CUPS, it prints colours fine. When I print from Windows, using Windows drivers (without Samba), it also prints fine. When I print from Windows through Samba/CUPS (drivers added using cupsaddsmb...), it gives me wrong colours: expected | result -------------------- yellow | blue blue | red red | green

Dear r-helpers, I wonder whether, given the "#rrggbb" representation of a colour, there is a simple way to select the complementary colour, also expressed as a "#rrggbb" string. Any suggestions would be appreciated. John -------------------------------- John Fox, Professor Department of Sociology McMaster University Hamilton, Ontario Canada L8S 4M4 905-525-9140x23604

Hi All, I have trying to do what I thought was a reasonably simple graph but I think I'm now going in circles with the colour. Attached is a picture of where I'm up to. The line creating this is: qplot(ageincgraph$age, ageincgraph$rate, position="dodge", stat="identity", geom="bar" ) + aes( colour=ageincgraph$era) +
