...;From this I want to get a new data frame which contains the z scores based on the values found in each row. For instance for element [C,y], I would like to calculate (-0.3602656 - mean(column y)/stddev(column y)). Thanks! -- Karin Lagesen, Ph.D. karin.lagesen at medisin.uio.no http://folk.uio.no/karinlag

...edian and quantiles, and possibly also all of the outliers somehow. Are there any facilities in R for doing something like this, or would I need to do this the hard coded way?

...invalid factor level, NAs generated Now, this is a pain in the neck. How can I merge these lists to the data frame and still have the value $twogrp as a factor?

...hints on how to do this? cbind just adds the vector onto the end, and I couldn't quite figure out if I could somehow say that the level should correspond to the PID.

...f these improved anything much. So, now I am wondering if any of you have any tips for how I can get something like I get in the x11() window which I can also store and potentially show other people. Thanks!

...data frame within the function, or should I get just the numbers out of the factors and input that into the function? Or is my solution way off from how things are done in R?

I know this is fairly basic, but I must have somehow missed it in the manuals. I have two vectors, often of unequal length. I would like to compare them for identity. Order of elements do not matter, but they should contain the same. I.e: I want this kind of comparison: > if (1==1) show("yes") else show("blah") [1] "yes" > if (1==2) show("yes") else

..., but I don't know how to incoporate that into the xyplot command, and I don't know how to specify which values I want plotted in each plot.

...ain of how to do this withhout doing it manually. The factor I am plotting against contains 17 levels, and I'd thus like to see if there is a somewhat more general solution available.

I am calculating some values that I am inserting into a data frame. From what I have read, creating the dataframe ahead of time is more efficient, since rbind (so far the only solution I have found to appending to a data frame) is not very fast. What I am doing is the following: # create data frame goframe = data.frame(goA = character(10), goB = character(10), value = numeric(10)) goframe[1,] =

...thin each group (I think). I have looked at hclust and it seems like it should be able to do what I want. However, I am unsure of how to use it to get what I am looking for.
