Re: [R] How to add error bars to lattice xyplot

Thank you, but on the example in use, it draws at each x a triplet of y from the same class linked by a segment. It is essentially a strip plot rather than a scatter plot... On Mon, Oct 11, 2021 at 10:28 PM Bert Gunter wrote: > > Your panel function needs to plot the points! See at b

Re: [R] assumptions about how things are done

I appreciate the feedback from several people. As noted, I do not want a deep philosophical discussion here and my main point remains not to expect software you "borrow" to do what you WANT but to accommodate it doing what it should. Most of the time, I would say that a I want a vectorized funct

Re: [R] How to add error bars to lattice xyplot

Your panel function needs to plot the points! See at below xyplot(Value ~ Concentration, group = Substance, data = df, pch = 16, cex = 1.2, type = "b", xlab=expression(bold(paste("Concentration (", mu, "M)"))), ylab=expression(bold("Infection rate")),

Thanks, now I got the bars (although without notch) but I lost the main plot: ``` xyplot(Value ~ Concentration, group = Substance, data = df, pch = 16, cex = 1.2, type = "b", xlab=expression(bold(paste("Concentration (", mu, "M)"))), ylab=expression(bold("Infection rate")), col=COLS, scales = list(

Hello, You can create a connection and read from it. desc <- "X:/Mkt Science/Projects/ tv/202109.ext/tsa.20210901.xml.zip" fname <- "20210901.socioDemos.a.xml" zz <- unz(desc, fname) Now read from zz. Example: xml <- XML::xmlParse(zz) Hope this helps, Rui Barradas Às 17:24 de 11/10/21, C

Hi have a large number of zipped files, each containing 3 xml files that I want to read. I would like to read one of the xml files without having to decompress each zip file first. If I run gzfile(path2zipped file) I get A connection with description "X:/Mkt Science/Projects/ tv/202109.ext/t

Re: [R] assumptions about how things are done

As noted by Richard O'Keefe, what usually happens in an R function is that any argument is evaluated either in its entirety or not at all. A few functions use substitute or similar trickery, but then expectations should be documented. I can understand that you want something like ifelse(y>x,x/y,

Re: [R] unexpected behavior in apply

Hi it is not surprising at all. from apply documentation Arguments X an array, including a matrix. data.frame is not matrix or array (even if it rather resembles one) So if you put a cake into oven you cannot expect getting fried potatoes from it. For data frames sapply or lapply is pr
