...connect lines between these two points (20 in all) to depict real change between the two timepoints. I have tried using stripchart which adequately plots the two lines of subject data points. Attempting to use segments however has been difficult. It seems that the segments command gives too many coordiate points - so where segments has: x0, y0, x1, y1 I really only have two coordinates for each point - pre to post I am sure that I am misusing the command but not sure if I should continue to try with segments or if there is another command that would be more appropriate. As always, thanks for an...

Hi, I'm new to this mailing list so apologies if this is too basic. I have confocal images 512x512 from which I have extracted x,y positions of the coordiates of labelled cells exported from ImageJ as a.csv file. I also have images that define an underlying pattern in the tissue defined as areas of different pixel values 0 or 255 (also 512x512) I've exported these images as .txt files. I'd like to use spatstat to look at how the individual c...

Hello dear all, A simple understanding question but I cannot find the answer anywhere. I use coordiates (longitude, latitude) in my study. I created a SpatialPoints class from those data and then I created a grid using the 'ascgen' command in the package 'adehabitatMR' like: ascgen(xy,cellsize=40). It worked out fine and my analysis is doing great. But I don't know what unit...

Hello, I would like to place some text that should appear in the same position of the graphic device, preferably outside the plotting area, regardless the x and y axes limits. How can I do this?

...of `labels'. Again, this may reflect a difference between S and R. The S manual states that `text' is a character vector to be plotted and `at' is an optional vector of positions. However, the R help states that `text' is a character string and `at' gives the location in user coordiates. This can be overcome by plotting `labels[i]' at `at[i]' within a loop. -- Stephen Harker s-harker@adfa.edu.au School of Physics Baloney Baffles brains: Eric Frank Russell University College http://www.adfa.edu.au/physi...
