Empirical density estimation
But for my reporting purpose, I need to generate a bell curve like
plot based on empirical PDF, that also contains original points.
Any idea would be helpful. Thanks,

Empirical density estimation
You need to re-read ?density and perhaps think again -- or do some study --
about how a (kernel) density estimate works. The points at which the
estimate is calculated are *not* the values given, nor should they be!
Cheers,

Christofer,
something like the following may get you what you want:
## get the kernel density estimate
dens <- density(Dat)
## estimate the density at

collumn error when exporting to Excel
Dear all,
I am attempting to export my results (data.frame) created with the help of a number of you to Excel.
In the procedure my column structure is however lost and all results are placed together into the first Excel column.
I have tried: write(), write.table(), write.matrix(), export() and have the same results. I Have checked the import/export FAQ and did a Google search to no avail.

HELP! Excel and R give me totally different regression results using the exact same data
Hallo,
I am totally confused why Excel and R give me totally different regression
results for the data below. If you know the solution, please enlighten me.
In Excel I used LINEST() and Data>Data Analysis>Regression and both
(fortunately) gave the same result.
The coefficients were:
/b0=1.16, b1=0.957, b2=0.024, R2=0.0027, adjusted R2=-0.017/

using barchart in lattice package and conditioning
I have the data structure below and I'm attempting to send it into

any output either. Deepyan's new Lattice book is amazing and there are

overlaying a set of 'grouping' lines on a plot from image()
Hi, I have a matrix that I am displaying via image. I would like to
obtain an image where the columns are 'grouped' (I have a grouping
variable). But I am not sure how how I can draw the lines to indicate
the grouping in the margin. I realize this is essentially waht heatmap
does but as I have a set of custom breaks and colors I wanted to
generate this via image. I can see that it is a

Placing text in a ggplot
I am attempting to graph 12 months of temperatures, delineate the months with a vline and place the names of the months at the top of the graph.
So far I have gotten everything to work except the names, despite getting a similar graph to work yesterday the day before yesterday with Baptise A's help. Can anyone suggest what I am doing wrong. Data set is below code.
Thanks.

ggplot 'annotate problem' again.
I had a problem annotating a graph last year ( see http://n4.nabble.com/Putting-names-on-a-ggplot-td907158.html#a907158 for the discussion)
Stefan (smu) provided a solution using annotate(). However I apparently did not update the graph file and,now, when I go back to the thread and try to use Stefan's solution it does not seem to work although I am sure that it did then.

problem with looping on sqlSave()
Dear R users,
I have a follow-up question on sqlSave().
Since most of the output from the tests I use are lists, I would like to
loop to export each element of the list and append it to the sheet.
Here is what I do:

Putting names on a ggplot
Can anyone suggest what I am doing wrong here. I am plotting
daily temperatures at Ottawa Ontario for 2008 broken down by
months, I seperate them by lines and want to put the names of the months
at the top of the chart ( with in the graphing area)
Everything is working as I want until I try to add the names of the months.
