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 and would love to keep using it.   Just wanting to know if this is

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 it: "An error occurred during an OLE operation sp~pagwf.dll

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. {{In the SigmaPlot

Dear R users I recently migrated from Statistica/SigmaPlot (Windows) to R (Linux), so please excuse if this may sound 'basic'. When running a nonlinear regression (V = Vmax * conc / (Ks + conc), i.e. Michaelis-Menten) on SigmaPlot, I get the output listed below: >>>Begin SigmaPlot Output<<< R = 0.94860969 Rsqr = 0.89986035 Adj Rsqr = 0.89458984 Standard Error of

Hello, I am quite a newbie under wine but I already achieve to run some MSapplication with it. For professional purpose I need to run sigmaplot. I installed it through wine on an ubuntu6.06, everything seems ok for instalation but when I launch it i got an error message : the windows is entitled "Graphics Page Library" and the message is "an error occured during OLE operation.

Hi, I?m trying to get smooth curves connecting points in a plot using "spline" but I don?t get what I whant. 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

There are 4 sets of array, each have 2 dimension data:x,y. And these data comes from bkde. I tried to plot them in one figure, but details of some lines, like peak and where 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

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, Eduardo

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...)

Hello, I'm just getting in to R, been reading manuals (thanks to all who provided pointers to good docs!), and messing with different commands. I'd appreciate a little help with this exploration, 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,

Hello I would like to make a graph with two variables, with 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.

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 be

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

Hi all: I have been using ggplot2 graphics for quite some time now and I really like it. However, I haven't used barplots enough to understand the arquitecture behind it. Can someone 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 Pond01 21.5

I have a table like the following. I want to fit Cm to Vm like this: Cm ~ Cl+Q1*b1*38.67*exp(-b1*(Vm-Vp1)*0.03867)/(1+exp(-b1*(Vm-Vp1)*0.03867))^2+Q2*b2*38.67*exp(-b2*(Vm-Vp2)*0.03867)/(1+exp(-b2*(Vm-Vp2)*0.03867))^2 I use nls, with start=list(Q1=2e-3, b1=1, Vp1=-25, Q2=3e-3, b2=1, Vp2=200). But I always get 'singlular gradient' error like this. But in SigmaPlot I can get the result. How

Hi everyone. I'm trying to break the y axis on a plot. For instance, I have 2 series (points and a loess). Since the loess is a "continuous" set of points, it passes in the break section. However, with gap.plot I cant plot the loess because of this (I got the message "some values of y will not be displayed"). Here's my code: library(plotrix); #generate some data x

Hi, I am sorry for this question, but I am trying to speed up an application.... I will need to fit many x-y data sets (input from text files) to 4-parameter Pseudo-Voigt peak function. Until now I used SigmaPlot macro to do it (enclosed just in case...) peaksign(q) = if(total(q)>q[1], 1, -1) xatymin(q,r) = xatymax(q,max(r)-r) [Parameters] a = if(peaksign(y)>0, max(y), min(y))
