Re: [R] Adding annotations to qplot from a data frame

Thank you for the many replies on this issue. I turns out qplot is not suited to multiple annotations, so the best suggestions were to use ggplot. The following worked for making an annotated stacked bar plot: ggplot(algaedata) + geom_bar(aes(x = year, y = cellsperml, colour = DIV, group = DIV

[R] Problems with labels and scaling in star diagrams

row (e.g. stardata[1,]) but that gives me an error "incorrect number of dimensions" when I try to generate the diagram. So, I seem to be unable to plot a single star diagram; it must be two or more. Many thanks - Euan. Euan Reavie, University of Minnesota Duluth.

[R] Using a string as a variable name - revisited

I would like to revisit a problem that was discussed previously (see quoted discussion below). I am trying to do the same thing, using a string to indicate a column with the same name. I am making "foo" a string taken from a list of names. It matches the row where "item" = 5, and picks the correspo

[R] map2poly - map lat/long cannot be unconstrained?

Using the maptools function "map2poly" I have created a map/polylist object - a map of the Great Lakes. My goal is to passively plot additional data on this map. Unfortunately I am not able to change (distort) the relative scale of the axes for the map, and so the sample points do not line up corre

[R] remove a row from a dataframe, row names disappear

I find this odd because it doesn't appear to happen in larger datasets. I have the following data set ENV with the first column set as row.names: > ENV TPlog 001S29H 0.601 002S42H 0.602 003S43S 0.779 004S43S 0.702 005S51H 0.978 006S52P 2.718 If I apply > ENV <- ENV[-1,] # remove f

[R] combining data frames in a list - how do I add breaks?

I'm a week-old R user, and have become stuck trying to create usable CSV outputs for post-processing. I am using the package Rioja, which provides small datasets of results. I am running several analyses in a loop and iteratively adding the results to a *list* ("combined"). Within each iteration I
