[ESS] Sweave with ESS and AUCTeX

Hi Gang: I’ve run into a problem that I can’t seem to figure out. I have a vignette that I am writing based on jss.sty (the JSS style) which comes with R. From the command line everything works as expected, i.e., “R CMD Sweave --pdf computing.Rnw” produces computing.pdf without issue.

Re: [R] Split charts with ggplot2, tidyquant

If you don't want to wait for a ggplot2 solution, here are two alternatives you can use right now: chartSeries(SPYxts) # or (with xts > 0.10 plot(SPYxts$SPY.Close) addSeries(SPYxts$SPY.Volume, type = "h") You might also try autoplot.zoo(), though I've never used it. On Thu, Jan 18, 2018 at

Re: [R] Perform mantel test on subset of distance matrix

Hi Andrew, Yes, you cannot have NA values in your matrices. Instead, you could incorporate a model matrix. See Legendre, P. & Fortin, M.J. Vegetatio (1989) 80: 107. https://doi.org/10.1007/BF00048036 for ideas. Sarah On Sun, Dec 31, 2017 at 12:55 PM, Andrew Marx wrote:

Re: [R] Split charts with ggplot2, tidyquant

Could you provide some information on your data structure (e.g., are the two time series in separate columns in the data)? The solution is fairly straightforward once you have the data in the right structure. And I do not think tidyquant is necessary for what you want. Best, Charlie --

Re: [R] MCMC Estimation for Four Parametric Logistic (4PL) Item Response Model

If you have the expression of the model, package nlsr should be able to form the Jacobian analytically for nonlinear least squares. Likelihood approaches allow for more sophisticated loss functions, but the optimization is generally much less reliable because one is working with essentially

Re: [R] MCMC Estimation for Four Parametric Logistic (4PL) Item Response Model

I know of no existing functions for estimating the parameters of this model using MCMC or MML. Many years ago, I wrote code to estimate this model using marginal maximum likelihood. I wrote this based on the using nlminb and gauss-hermite quadrature points from statmod. I could not find that

Yes, and the structure is obviously case-insensitive. More troublesome is probably that there can be multiple ACADEMIC-EMPHASIS entries, which can be tricky to tidify. Also one would need to figure out what is the meaning of lines like (DEFPROP BOSTON-COLLEGE0 T DUPLICATE) -pd > On 18 Jan

That's a nice example of why Lisp is both powerful and terrifying - you're looking at a Lisp *program*, not just Lisp *data*, as Lisp makes no distinction between the two. You just read 'em in. The two definitions at the bottom are function definitions. The top one defines the def-instance
