plotrix::thigmophobe could usefully coerce to numeric...
thigmophobe.labels() fails with error when supplied with an array
resulting from tapply (example below).
The error originates in thigmophobe()
I know the help page says 'numeric vector' but it would be kind of nice
if it worked with numeric things of class array too. I think it would
need no more than a couple of as.numeric() calls in thigmophobe itself,
or (simpler but slightly less

How to avoid overlapping labels
Hi Remko,
thanks for your answer. but i do
not really understand how to use the commands.
if i want to use thigmophobe.labels(x,y,) do i need to identify the xy
coordinates for each point first and then manually move every point? and if
i neet to do so how to use the identify() function?
or is there any possibility to automatically place the labels in the best
position?

help with formula and data= argument
Sorry for posting this twice, but I still have not solved this problem
and am hoping for some assistance.
I am attempting to write a function that is flexible enough to respond
to the user providing a formula (with a data= argument) or not (similar
to plot(x,y) versus plot(y~x,data=data)). I have found a method to work
with this in a simple case but am having trouble determining how to

Covered Labels
Dear All!
How can I cope with overlapping or covered labels (covered by labels
from other data points) in plots?

Stting non-overlaping text positions
Dear List
I am having problems to set text labels in a scatter plot. At some areas dots
are close and labels overlap and texts cannot be read. I have too many dots
to adjust this manually. Is there any function that will calculate the label
offsets to avoid this overlapping problem?
Thanks

arrangement of crowded labels
Dear R users
I'm looking for algorithms that assist in spreading out crowded labels, e.g.
labels of points in a scatter plot, in order to obtain a nicer visual
appearance and better legibility.
I'm probably just stuck because I didn't find the right key words for a
successful search on the R websites or in the mailing list archives.
Any hints are appreciated.

Avoiding overplotting of text.
Hi all,
I am plotting some data, and use text() to get variable names next to
points on the graph. What is the best way to make sure that these text
labels are readable and not overlapping when two datapoints are close?
I've tried using jitter(), but the effect is random and doesn't always
give a good result.
Any suggestions would be most appreciated.
Best regards,
Gustaf

overlapping labels
Good evening,
I am trying to add labels to the point of a simple plot, using the
text() function; the problem is that sometimes, if two points are too
close to each other, labels overlap and are no longer readable.
I was wondering whether there are options that I can use to prevent this
overlapping (by, for example, placing labels alternatively above and
below the plotted curve), or whether I

Graph color
Hi all I want to apply different colors on a simple plot:
If I type par(br="gray") before a plot it puts all the image in gray but
(imagine I run a simple plot) want to let the centrall box (where the dots
are plotted) in white or image in lightblue.
Can anyone guide me to apply this second step (make the box where the series
are plotted in different colours).
Thanks in advance.

R implementations of scatterplot/map labeling algorithims?
Dear R community
In a current paper, I'm (briefly) considering the topic of producing
scatterplots or maps with point labels positioned in such a way as to
minimize label overlap and occlusion. This is a topic with a large, but
scattered literature. In CS, it is considered NP-hard, but there are
a variety of approximate solutions. The most complete bibliography I've
found is

Need help with pointLabels()
Hello R-list,
I am plotting a weighted linear regression in R. The points on my chart are
also scaled to sample size, so some points are large, some are small. I have
figured out everything I need using the plot() function: how to plot the
points, scale them by sample size, weight the linear regression by sample
size, plot that line, and plot the labels for the points. However, although

Automatic anchors for text boxes
Hi All,
I'm struggling to add text automatically to plots. I have a series of
scatterplots that I have stored in a script because the underlying data
changes often and the plots need to be regenerated. I use the scatterplot
function (defined in Rcmd, I believe). When one of the variables is a
factor, a boxplot is drawn over the scatter of the other variable. In the
case where x is a

Hi all.
1) If I have a dataframe with variable names as follow: PC1 PC2 ... PCn and I want to pass only some of them to a function, e.g.
glm(resp~from PC1 to PC10, PC15, etc.,...)
is there a faster way than simply writing each variable name in the formula?
