Good Morning: I have attached a text file with one hundred thirty six observations. I would like to create a qq plot with the following features: 1. Observed values on the y-axis. 2. Normal approximation line on the plot. 3. X-axis with vertical reference lines at the following percentiles of the data: 1, 10, 20, 50, 80, 90 and 99. 4. Data appearing on the plot as distinct points. I assume that

Good Evening R-Help Community: I have attached a file that contains the output from sessionInfo() and a summary of my Win XP system. I am?running R 2.12.0 and using Tinn-R 2.3.6.2 as my interface. When I attempt to call either the doBy or coin packages R generates an error that I do not understand and have so far not been able to resolve by searching R resources. I exchanged a couple of

Good Evening: I am putting together a large report with plots created in R, V 2.12.0. Most of the plots are created using ggplot2 V0.8.9. I use R's pdf() command to export the plot to a pdf file. I am exporting the plots and attempting to edit the title text in?Inkscape?primarily because ggplot2 does not support superscript or subscript formatting in the title text. For the report I am

Good Morning: I've read many, many posts on the r-help system and I feel compelled to quickly admit that I am relatively new to R, I do have several reference books around me, but I cannot count myself among the fortunate who seem to strong programming intuition. I have a data set consisting of 1637 observations of five variables: tensile strength, yield strength, elongation, hardness and a

Good Morning: I posted an initial question a few days ago and I received some good advice from two R experts. I have re-examined the Davison-Hinkley text paying close attention to the examples of the boot() and boot.ci() in that text and the single example of a similar process in the MASS book (not the MASS package manual as I initially misunderstood). I think I understand how the stratified

Good Evening R Community: I believe I understand the basics of using the boot() bootstrap resampling function in the boot() package. I have not had any trouble creating a boot.object to which I apply the boot.ci() function to calculate one or all of the available confidence intervals. What I am not sure about is if this set of functions can generate more than one confidence interval of one or
