[R] how can i fix the color for different image plot?
Hi, i defined the colors as follow for image function in R, mycola=c(#00FF00,#0DF200,#1BE400,#28D700,#36C900,#43BC00,#51AE00,#5EA100,#6B9400,#798600,#867900,#946B00,#A15E00,#AE5100,#BC4300,#C93600,#D72800,#E41B00,#F20D00,#FF) So when i use this color set to plot different data matrix which have different max and min value, the same color in different figure represents different value. for example ,i have two data matrix,one with min= -2,max=3.5;the second with min= -3,max=2.5;And i want to fix -3 to be the most blue(#00FF00),3 the most red(#FF),what can i do ? That is vales less than -3 will be plotted as -3, so for vales greater than 3. Any suggestion? Thanks in advance.

Re: [R] Is there a function in R can help me to plot such a figure?
This figure is the plot of prototype of a Self Organizing Maps(SOM) result.The numeric data is a M*N matrix, M rows and N columns.color2D.matplot can transform the numeric matrix to a color matrix ,but i have to put them in hexagon cells to reveal their topological structure( M hexagon cells in a column,N hexagon cells in a row). It seems that i have to use the GRID package in R.

I don't know of an R function that does hexagon cells, although it wouldn't be impossible to program. What is the numeric data behind such a plot?

[R] How to add a line on the boxplot
Hi, I have a data frame, df=rnorm(1000) dim(df)=c(100,10) And i can get the boxplot, boxplot(data.frame(df)) So how can add a line (aline) on the existing boxplot,eg, aline=apply(df,2,max) Thanks in advance.

Re: [R] How to add a line on the boxplot
Thanks The first method,i get many lines,using the second,i get segments.I actually need one line with y coordinate defined by aline,x along the boxplot.

Example: df - rnorm(1000) dim(df) - c(100,10) boxplot(data.frame(df)) aline - apply(df, 2, max) # , now you might want either abline(h = aline, col = green, lty=dotted) # or segments(seq(along = aline) - 0.2, aline, seq(along = aline) + 0.2, aline, lwd = 2, col = red) Uwe Ligges [[alternative HTML version deleted]] __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
