I am very new to R so forgive me if this seems basic but I have done extensive searching and failed to come up with the answer for myself. I am trying to label a boxplot I have created with the values for the median, upper and lower quartiles and max and min values. I have been unable to do this or find anything on the net to say how it might be done. Is this possible and if so how? Regards,

I need to make weighted boxplots. I found that ggplot makes them. I would however like to label them with the boxplot statistics (the median, q1 and q3). In the boxplot function in r-base, I could output boxplot statistics and then write a text on the plot to place the labels. How would one do it with ggplot? Vikas

Hi, I'm trying to match two data frames in order to replace the boundary values in a dataframe.1 with values in dataframe.2 ONLY where the pair id1 id2 matches between the two data frames. Eg. > dataframe.1 ... id1 id2 boundary 3307 1095 1108 438.691 3308 1095 1109 438.691 3309 1095 1121 438.691 3310 1096 1109 438.691 ... 3345 1108 1120 438.691 3346 1108 1121 438.691 3347 1108

If you multiply a matrix by its inverse you should get an identity matrix. In R, you get an answer that is accurate up to about 16 decimal points? Why can't one get a perfect answer? See for example: c(5,3)->x1 c(3,2)->x2 cbind(x1,x2)->x solve(x)->y x%*%y Vikas Rawal ============================================== This Mail was Scanned for Virus and found Virus free

For boxplot(), is it possible to pass in a parameter to change the default way that the 1st and 3rd quartiles are computed? (specifically, I'd like to use type 6 described in the quantile function). Also, what are the options for how outliers are computed, and how can one change them? Thank you [[alternative HTML version deleted]]

This issue has been discussed on this list before but the solutions offerred are not satisfactory. So I thought I shall raise it again. I want to merge two datasets which have three common variables.
