Let's say I have the following string: str <- "P = 0.0, T = 0.0, Q = 0.0" I'd like to find a function that generates the following object from 'str'. list(P = 0.0, T = 0.0, Q = 0.0) Thanks! -- http://mutualism.williams.edu

Full_Name: Manuel A. Morales Version: 2.8.1 OS: Linux Submission from: (NULL) (137.165.199.246) When fitting a model in nls using the algorithm port with constraints and the shorthand parameter[factor] in the model, I get the following error message: "Error in nls_port_fit(m, start, lower, upper, control, trace) : (list) object cannot be coerced to type 'double' In addition:

Hello list members, I'm looking for a way to force the results of a crosstabulation to be square - that is, to include 0 values. For example: table(letters[1:4],letters[c(1:3,3)]) yields: a b c a 1 0 0 b 0 1 0 c 0 0 1 d 0 0 1 I would like to return: a b c d a 1 0 0 0 b 0 1 0 0 c 0 0 1 0 d 0 0 1 0 Any suggestions? Thanks! -- Manuel A. Morales

Hello list, I'm trying to fit a model like beta[trt]/(1+alpha*x) where the data include some grouping factor. The problem is that the estimate for alpha is undefined for some of the treatments - any value greater than 20 is equally good and a step function would suffice. Ignoring the grouping structure, I can fit this using nls with the port algorithm by restricting the upper value of alpha

Hola, estoy representando los datos Duncan de la libreria car y cuando hago un gráfico lattice observo que la profesión "architect" aparece en dos subgráficos que no se corresponden con su categoría. Alguien sabe el motivo? Os adjunto un fichero con el código y el gráfico resultante. Gracias, Manuel [[alternative HTML version deleted]]

Hello! I need to install Samba on AIX and the AIX folder in https://download.samba.org/pub/samba/Binary_Packages/ has only a readme that points to the following address: http://pware.hvcc.edu/ However that host is down, what is the best way to get Samba binaries for AIX? Thanks!

Hello list. I'm using R from the gnome-terminal in Fedora. My preference is to write programs in VIM, and then source the file from R, or copy and paste the lines into the console. I'm wondering if there is a way to increase the "paste buffer" as an alternative to "sourcing" large analyses. As was mentioned in a recent thread on Linux GUI's, I find that if I paste

Hello, Is there a way to get augPred to work with lme if a subset statement is used? For example, if I modify the example from ?augPred.lme to include a subset statement, I get the following error: fm1 <- lme(Orthodont, random = ~1, subset=distance>19) augPred(fm1, length.out = 2, level = c(0,1)) Error in tapply(object[[nm]], groups, FUN[["numeric"]], ...) : arguments

Dear list members, In some of my functions, I attach the data internally to allow subset commands or to specify a data frame. This works well except for cases where there is a "masking" conflict (which returns a warning). I see some alternative listed in ?attach, but I'm not sure which of them do what I'd like. Any suggestions? Below is how I've been setting up my

Hi, I would like to have lineplot.CI and barplot.CI to actually plot confidence intervals , instead of standard error. I understand I have to use the ci.fun option, but I'm not quite sure how. Like this : > qt(0.975,df=n-1)*s/sqrt(n) but how can I apply it to visualize the length of the student's T confidence intervals rather than the stdandard error of the plotted means

Dear r-helpers, Spencer Graves and Manual Morales proposed the following methods to simulate p-values in lme4: ************preliminary************ require(lme4) require(MASS) summary(glm(y ~ lbase*trt + lage + V4, family = poisson, data = epil), cor = FALSE) epil2 <- epil[epil$period == 1, ] epil2["period"] <- rep(0, 59); epil2["y"] <- epil2["base"]

Dear list, A while ago, I posted a question asking how to use data or subset arguments in a user-defined function. Duncan Murdoch suggested the following solution in the context of a data argument: data <- data.frame(a=c(1:10),b=c(1:10)) eg.fn <- function(expr, data) { x <- eval(substitute(expr), envir=data) return(mean(x)) } eg.fn(a,data) I've

Is there a way to adjust the font size for axis labels when using persp()? The parameter cex works for adjusting the global font size, but I can't seem to make cex.lab or cex.axis work for adjusting these values independently. Or, is there a preferred method for making surface plots in R? I'm using R version 1.8. Thanks, Manuel

Hello list, Is anyone aware of a non-lattice-based alternative to xyplot()? Thanks! Manuel -- http://mutualism.williams.edu

Hello, Is anyone else having problems with the ssh session output stalling when ssh'd to another system and the command is running via sudo and a pager is being used (e.g., more)? Too highly reproducible :( to date, all known occurrences have involved Centos 4.3 servers; makes no difference whether client is RHEL WS 4.3, Centos 4.3 or FC 5 or WinDoze. Makes no difference if terminal

All, When logging into an HP-UX 10.2 system from a Windows NT machine running Cygwin and openssh 2.9p2, control-c sends a sigint to the ssh client on the NT system, thus killing the ssh process. Interestingly enough, this behavior is only observed when using X11 forwarding. I can eliminate the behavior by changing clientloop.c to ignore SIGINT (signal(SIGINT, SIG_IGN) ) but then I'm bak to

Yeah, I get that they are async. What happens is that the background process is not doing anything when the process gets a SIGINT. I.e. the background process is just listening on its standard input. AFAICT for an interactive process such a SIGINT is just swallowed, with a newline outputted to the terminal. But apparently, for this background process, it is not swallowed, and it is triggered

Hi All, I realize that this is not a really nice reprex, but anyone has an idea why a background R session would "remember" an interrupt (SIGINT) on Unix? rs <- callr::r_session$new() rs$interrupt() # just sends a SIGINT #> [1] TRUE rs$run(function() 1+1) #> Error: interrupt rs$run(function() 1+1) #> [1] 2 It seems that the main loop somehow stores the SIGINT it
