I am interested in testing two similar nls models to determine if the lines are statistically different when fitted with two different data sets; one corn, another soybean. I know I can do this in linear models by testing for interactions. See Introductory Statistics with R by Dallgaard p212-218 for an example. I have two different data sets I am comparing to lai. ci.re should have very

Thanks it worked for me. I wanted to plot days since planting on x-axis 1 and years on x-axis 3. LAI_simulation$Date <- as.Date( LAI_simulation$Date, '%Y/%m/%d') LAI_simulation$Date <- as.integer(LAI_simulation$Date - as.Date("2009-10-07")) plot(LAI~Date,data=LAI_simulation,xlab="Days since Oct, 7,

Is there a "canned" function in R for finding the standard error of the mean? I have tried > sem <- function(x) c(mean =mean(x), + SEM = stdev(x)/sqrt(length(x))) > sem(pnet.lai) Error in sem(pnet.lai) : couldn't find function "stdev" It looks like there is no stdev function in R Thanks, Kirk Kirk R.

[In future, please press reply all as there might be others in the mailing list who can help you] Without a (short) reproducible example, it would be difficult to say. BTW, I think you have mistyped the error/warning message. Does it actually say "cannot compute _correct_ p-value" or "cannot compute _exact_ p-value". See example below. > wilcox.test( 1:3, 1:10 )

Dear all, I have several questions regarding fisher.test() in R, and I'd highly appreciate any help with it. I have a group of observations, each having people's income, and an indicator of whether selected in or out a program. I want to test the difference between income of people who are in and out. Because the distribution is far from normal, I decide to use the fisher's exact

Dear all, I have another question about fisher.test: Is there any way to save the resulting p-value in a matrix or file after a loop as below? for (i in 1:42) { # testing difference in income(pinc) between people in # (with in1=1) and out (with in1=0) of the program for # group i fisher.test(m$pinc[m$group==i], m$in1[m$group==i], workspace=40000000, hybrid=F)} When I run this loop, there is no

Hi LLVM community, I am writing a custom pass for analyzing the dependence information for the memory access within a loop. I found “LoopAccessLegacyAnalysis” class useful, however I m not able to obtain information from that pass. Here is what I did to get the information: // require pass virtual void getAnalysisUsage(AnalysisUsage &AU) const {

My dns (bind9) server for my Samba AD has messed up. W10 workstations are having connection issues to say the least. When I dig into the Sambawiki documentation regarding /BIND9_DLZ_DNS_Back_End/ the first thing I notice is the change that occurred at Samba v4.8.0. That is the change of "|/usr/local/samba/_private_/named.conf|" to

Any reason why portaudit and its associated infrastructure was not announced to this list or security-notifications? I recently discovered it, and discovered the feature was added to bsd.port.mk in the beginning of feburary. Seeing as the security officer apparently (without announcement) no longer issues security notices (SNs) for ports, I am assuming that portaudit has replaced SNs entirely,

How can I convert date to continuous variable staring from 1. I tried as.numeric but R starts counting from default January 1, 1970 while my data start Oct 7, 2009. I need to do this conversion to plot the date on two x-axes (1 and 3). Ex; Date LAI 10/7/2009 0 10/8/2009 0.004173 10/9/2009 0.009997 10/10/2009 0.009998 10/11/2009 0.009999 10/12/2009 0.009999 10/13/2009 0.009999 10/14/2009 0.009999

The issue is that readLines() tries to seek (for reasons I don't understand) in the non-blocking case, but silently fails for "stdin" since it's a stream. This confused the buffering logic. The fix is to mark "stdin" as unable to seek, but I do wonder why readLines() is seeking in the first place. Anyway, I'll get this into patched ASAP. Thanks for the report.

Hi, Has anyone had success in building R source with Visual Studio? I followed the instructions in README.packages, but failed on the very first step, where it's looking for R.dll. I looked through R source and couldn't find the file. Can someone point me to where this file is located or generated? Thanks! Sincerely, Jennifer

Forgive me if this isn't relevant, but: are you stripping off the output you need (e.g., parameter estimates) and throwing away what you don't (e.g., residuals)?
