Re: [R] Problems getting symbols() to show table data
Thanks. I don't think I would ever have worked that twist out. It is perfect.

Re: [R] Problems getting symbols() to show table data
Thanks, balloonplot() is great and gets me really close to what I am after. However it then brings me to a slightly different problem - I wonder if anyone can suggest where I am going wrong? Again with simplified data ( http://n4.nabble.com/file/n1890724/test-data.txt test-data.txt ): Aug-03 Nov-03 Feb-04 May-04 Aug-04 Row1 1 -1.1 1.21.3-1.4 Row2 3 -3.1 3.23.3-3.4 Row3 5 -5.1 5.2 -5.3 5.4 library(gplots) Read_data=read.table(C:/files/test-data.txt, head = T) number_rows = nrow(Read_data) number_cols = ncol(Read_data) matrix_data = as.matrix(Read_data) row_names = rep(rownames(matrix_data),number_cols) col_names = rep(colnames(matrix_data),number_rows) x11(width=120, height=80) balloonplot(col_names, row_names, abs(matrix_data), dotcolor = c(lightblue, red)[(c(matrix_data) 0) + 1], show.margins = FALSE, cum.margins = FALSE, xlab = , ylab = , label=T, label.lines= F, colsrt=90, sorted = F, rowmar=3, colmar=2.5,) This gives this graphic: http://n4.nabble.com/file/n1890724/R_upload.jpeg R_upload.jpeg . The data colours go in the right places within the grid - i.e. with the correct numbers. However the numbers themselves are mixed up within each row. Transposing the matrix_data within balloonplot() doesn't correct it. Can someone see something simple that I am missing here?

[R] Problems getting symbols() to show table data
Hello, I am trying to create a graphic to help me visualise data. A (very simplified) sample of the data is http://n4.nabble.com/file/n1839676/circle_data.txt circle_data.txt : Aug-07 Nov-07 Feb-08 data1 1 1.5 -1 data2 1 1.2 1.6 data3 1.31.41.8 data4 1.3 -1.21 What I am trying to achieve is: * Circles representing each item of data, * The circle size represents the number, * The data is arranged in rows and columns, similar to the table layout (i.e. dates along the top or bottom), * Positive numbers are blue circles, negative red circles. I have used info from lots of previous posts on symbols() to get me some of the way, but I am still far off getting it to actually work, with the result that I think I may be heading in completely the wrong direction. I can create a grid of circles with the right number of dimensions: Read_data=read.table(C:/files/circle_data.txt, head = T) number_rows = nrow(Read_data) number_cols = ncol(Read_data) xaxis = rep(seq(1,ncol(Read_data),1),nrow(Read_data)) yaxis = rep(seq(1,nrow(Read_data),1),ncol(Read_data)) zvalues = rep(0.1,(number_rows*number_cols))#This is just a dummy vector symbols(xaxis, yaxis, circles = zvalues, inches = FALSE, xlab=, ylab=) axis(2, at=c(1:number_rows), rownames(Read_data), las = 1) axis(1, at=c(1:number_cols), colnames(Read_data)) BUT... this only uses dummy values - I can't think how to get the table into a form the symbols() function can use. I tried as.vector() unsuccessfully. Also, this code simply overwrites the x and y-axis labels, which looks terrible: again, I can't think how to get this right from the start. On getting positive values to be blue and negative red, I had assumed I could just split the data into two and plot separately: Data_positive = replace(Read_data, Read_data0,0) Data_negative = -replace(Read_data, Read_data0,0) However, this quick trial below gives little dots for zero values, so it is not a perfect result: zvalues_pos = rep(c(0.1,0.2,0), 4) #Dummy vector for positives zvalues_neg = rep(c(0,0,0.3), 4)#Dummy vector for negatives symbols(xaxis, yaxis, circles = zvalues_pos, inches = FALSE, xlab=, ylab=, bg=blue) symbols(xaxis, yaxis, circles = zvalues_neg, inches = FALSE, xlab=, ylab=, bg=red, add=TRUE) [Incidentally, I have tried to work through this example ( http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=152 http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=152 ) but I am out of my depth in making sense of the code.] Any help would be gratefully received.
