Hello, I have a data set with 15 variables, and use "pairs" to plot the scatterplot of this data set. Then I want to plot some circles on the small pictures with high correlation(e.g. > 0.9).
First, I use "cor" to obtain the corresponding correlation matrix (x) for this scatterplot. Second, use "seq(along = x)[x > 0.9]" to find the positions of the small pictures with 0.9 correlation, but "seq" can just find the sequence position row by row for the matrix, not a real position (like "rowNumber, colNumber"). Is any function for that? Third, use "Symbols" to plot the circle on these small pictures, but seems it can't do that. Also, I don't know how to adjust the thickness and radius of the circle plotted by "Symbols". Please give me some ideas! Thank you, Shengzhe ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
