Is it possible for R to import a SigmaPlot file?
I recently received a Sigmaplot file (*.jnb) from a customer and would like to know if I can input it to a data frame and then manipulate the data in R.
I did a search on Google and on RSeek (www.rseek.org), but did not get any good hits. Thank for any feedback and insight you can provide.
P.S. Love the flexibility of R a...

No success running SigmaPlot
Hi!
I strongly rely on SigmaPlot for scientific graphs, actually one of the few windows programs I still need. I use a licensed copy but a trial version can be downloaded here:
http://www.sigmaplot.com/products/sigmaplot/
I could install several versions of SigmaPlot (8, 9, 11) but I always get the same error when I try to run i...

Runtime error while I run sigmaplot 11 on fedora 10
I am trying to run sigmaplot 11 on wine 1.1.18 on Fedora 10
When sigmaplot opens another window opens and says the following:
It says "error occured during an OLE operation"
sp~pagwf.dll.\gpu_doc.cpp(687) 8e000010
Please let me know if there is a fix for this,

SigmaPlot and Windows Vista
Dear Colleagues,
I've tried to run my SigmaPlot 6.0 in a computer with Windows Vista
but have got the message
Cannot open or create 'C:\PROGRAM FILES\SPW6\LOCKFILE.SYS'
every time I try to start the software.
Does anybody know what I should do to overcome this problem?
Thank you all in advance.
Best regards,

Fitting controlled released data
...sing R for a while and I
find it incredible.
I was just wondering whether someone has ever written a library to calculate
the best fit of experimental data to some controlled release models, having
only the release cumulative drug release at given time points. For example,
there is an extension for SigmaPlot
http://www.sigmaplot.co.uk/products/sigmaplot/productuses/prod-uses15.php
which allows rapid fitting of 5 standard model. I prefer to use free
software and therefore I rather use R than Sigma Plot.
Is there anyone who can help?
Thank you very much
Marco

Smooth line in graph
...Eg.:
x<-1:5
y <- c(0.31, 0.45, 0.84, 0.43, 0.25)
plot(x,y)
lines(spline(x,y))
Creates a valley between the first and second points, then peaks at 3rd,
and another valley between 4th and 5th. I?m trying to get a consistently
growing curve up to the 3rth point and then a decrease like with
SigmaPlot spline curves or with Excel.
I tried with different spline arguments and also lowess and loess, with
no success. Any ideas?
Thanks.

nls: Fitting two models at once?
Hello,
I'm still a newbie user and struggling to automate some analyses from
SigmaPlot using R. R is a great help for me so far!
But the following problem makes me go nuts.
I have two spectra, both have to be fitted to reference data. Problem: the
both spectra are connected in some way: the stoichiometry of coefficients
"cytf.v"/"cytb.v" is 1/2.

Nonlinear regression question
Dear R users
I recently migrated from Statistica/SigmaPlot (Windows) to R (Linux), so

When running a nonlinear regression (V = Vmax * conc / (Ks + conc), i.e.
Michaelis-Menten) on SigmaPlot, I get the output listed below:

Problem about plot scale
...e it locate, have diminished since one set of array have
fairly high y value.And another array have lots of y value near zero,
like 1e-20, 1e-10, like a long tail, while the highest y value of
these arrays is 1e-4.
Does R have the function to cut some range of y value? The
corresponding function in sigmaplot is break in which we could define
break range to omit some meanless range of y value.

Plot symbols dimensions
I am writing some code to obtain publication-like plots (like the ones can be obtained with
SigmaPlot). I am not able to find the dimensions of a point. Parameters like cex make you able
to make it bigger or smaller but I need to know the exact dimension (in relative coordinates :
if my plot is 640x480 a dot plotted with cex=1.5 will be...)

Newbie: Barchart Gray with White Grid?
...ploration, and I hope that my
question is relatively easy to answer (probably, there's a simple way
to do what I'm working toward).
R's statistical functions are coming along easily enough, but graphics
seem to be a little tougher for me, probably because I'm used to
working in SigmaPlot. As an exercise, I tried to create a gray bar
chart with white grid overlay, like the one on page 128 of Tufte's
"Visual Display of Quantitative Information." I figure this would
cover a lot of the basic techniques that I'll need for "real" work. I

Two axes with different scales
...h different units,
so I would like to have two y-axes, one on the left and one on the right
with different scales. Is this possible?
I have searched through all the documentation I could find on the R homepage
without luck and I like R very much and would rather not resort to using
something like SigmaPlot for this seemingly simple thing.
E.g. plotting the concentration of Oxygen and it's isotopic composition in
the same graph.
Thanks, Henrik

Linear regression - R^2
Hello,
I was doing a linear regression with the following formula:
*lm(y~x+0)*, so it passes through the origin. But when I called the summary
of the regression i saw that R squared is abnormally high (it's a lot lower
in other programs such as SigmaPlot and MS Excel).The manual explained the
cause of the difference (because of the different computing method), but
what should I do to get the same R^2 in excel and R?
WITHOUT PASSING THROUGH THE ORIGIN:
R^2: Multiple R-squared: 0.9711, Adjusted R-squared: 0.9654
In MS Excel: 0,9711

Can I Compile R with MS Access 2003 Developer Extensions?
Hi:
I have an application that uses MS Access as front end interacting with Excel,Word,Sigmaplot and R in the background. I use the programs to do different tasks but I mainly use R to create graphics on my Access forms without having to manually open R.
To make this short, I was wondering if R can be compiled from Access using the Developer Extensions. I know that the MS office programs can b...

ggplot2-barplot
...eone show me how to make this simple barplot graph with ggplot2? I want "PondName" along the x axis and "avgWt" along the Y axis which represents the avgWt by each Pond.
PondName avgWt

Pond02 17.8
Pond03 17.8
Pond04 17.8
Pond05 16.375
Pond06 21.5
Pond07 21.5
Using sigmaplot or Excel is a simple task but I can't get it to work with ggplot2. I was trying:
qplot(PondName,data=mydata,geom="bar") + geom_bar(fill=factor(PondName))
but I don't get the desired results. Thanks

in SigmaPlot I can get the result. How can I get with R.
