Sorry all for these two easy questions: First, I have a matrix with trhee columns: A= Name Eight Puntuation Pepe 1,85 10 Paco 1,7 7 Pablo 1,82 6 I want to scatter the two columns (I could use pairs or other functions...) but the only doubt is that I cannot find the way to add in the associated intersection (the point scattered) the label "Pepe" "Paco" and so

Hi, I have finally installed TeachingDemos trough zip file and installed on lbrary. One new question: I want to draw a line (like abline) on diagonal or the result of running a ols. How can I do it. On the other hand, I want to mark the length on each sub plot y axis. It is possible? My function is sca<-function(){ z2<-read.table("Ase.txt",header=T)

Hi all, I want to plot trough pairs() plot a matrix with 4 columns. I want to make a trhee plot in a graph. Plotting pairs colum 2,3,4 on y axis and 1 on X axis. You mean (a plot with three graphs) ommitting the first pair with itself. And only the pairs with colum 1 with the other not all pairs. I. e. this matrix 4177 289390 8740 17220 3907 301510 8530 17550 3975 316970 8640 17650 3651 364220

Hi I have an output data Data.csv this style: ,"V1","V2","V3" 1,"-9552","9552","C" 2,"0","9653","0" 3,"9614","9614","V" 4,"0","9527","0" 5,"-9752","9752","C" 6,"0","9883","0"

I imagine I make a function whose results are a Matrix Z How cn I save in a txt or excel file the result of apply my function? something similar to save Z.txt. Thanks in advance. [[alternative HTML version deleted]]

Hi all, I´m using titt<- expression(paste("R con ventanas de 200 ", italic(datos))) And it works properly on a plot(...,main=titt,..) But if I want to add an improvement to avoid typing n on the plot so that n<-200 titt<- expression(paste("R con ventanas de ",n, italic(datos))) It doesn´t recognize that n is a "variable" and adds "n" letter

Hi all, I have two vectors (columns) called "efinal" and "efinal 2". I want to plot them on the same plot and "draw" a shaded area beween the two lines using function polygon I have tried all but I don ?t understand the polygon area, can you help me with examples? plot(efinal,type="l",ylim=range(min(efinal2),

Hi I wrotte this function but when I get the "tmp.xls" file it shows data in a rare way. I mean not appears a matrix with 2000 rows and 100 columns. Can anyone help me, guide me? kim<-function(){ tmp<-randz<-matrix(rnorm(200000, mean=0,sd=0.01 ),2000,100); dim(tmp) write(tmp,file="tmp.xls") Thanks in advance. On the other hand, everytime I execute a function

Hi I want to simulate random numbers normal distributed with this size (2000,10000). I tried this but my computer exhaust there is a fast way to make it? randz<-matrix(rnorm(2000000),2000,10000) [[alternative HTML version deleted]]

Hi all, Imagine I have a matrix and the first colum is a list that repeats the same names, I want to sum the second column on each unique name on first column. Imagine this: Pepe 2 Pepe 3 Pepe 4 Jose 2 Jose 5 Manuel 4 Manuel 2 I want to make a new matrix that calculates and recognizes that there are 3 different names ans sum second column. But a priori I don´t know the list of the different

Hi all, I have a matrix dd with dates and data. i WANT to create a grpah with shade between the line and the zero axis. I?m trying to use polygon but something doesn? t work Imagine. I want to plot g<-read.table("dd.txt", col.names=c("fecha","DP")) g$fecha <- as.Date(g$fecha, format="%d/%m/%Y") t<-g$fecha st<-length(g$DP)

hi, I am trying to label data points within a scatter plot using thigmophobe. While the data set consists of about 3000 points I only would like to label a subset of these points. I read the x and y coordinates in from a txt file and define them as: MLPM1<-log2(Ratio.M.L.G2.PM) HLG2<-log2(Ratio.H.L..G2.PM) the names and a corresponding ID are read in from the same txt file as:

Hi Remko, thanks for your answer. but i do not really understand how to use the commands. if i want to use thigmophobe.labels(x,y,) do i need to identify the xy coordinates for each point first and then manually move every point? and if i neet to do so how to use the identify() function? or is there any possibility to automatically place the labels in the best position? >MatArab <-

Hi all, Imagine I have a matrix G with N rows and M columns So L=NxM is the number of different cells in my matrix. I want to create a column vector F whose size will be F(L,1) So the fisrt row in F is G(1,1) Second row in F is G(1,2) When we arrive to a point M the element M+1 will be G(2, 1) Element M+2 will be G(2,2) and so on. I´m trying but allways error.... Easy Example: G= 2 3 4
