This doesn't sound right. When you use expression() it freezes the syntax as the expression you wrote, so expression(paste(x^2,"[", m^2, "]")) is a perfectly valid plotmath expression. The expression() call is _not_ an "inverse" of paste because the presence of paste is supporting the inclusion

Re: [R] [External] Re: [External] Adding a superscript 6 to a number

It is a generalization. Don't use paste() and expression() together because paste is a sort-of inverse to expression. In this example I start by typing several characters, and the result of paste(expression()) is a string containing the characters I initially typed. > expression(12^6)

Re: [R] A Labeling the median

Hi Greg, I think what you want is: mtext (side=4, "median", col="firebrick4", at=median(walk_seconds)) "adj" defaults to 0.5 and is usually okay. It looks to me as though mtext has taken your _character_ strings as non-numeric and then tried to work something out with par("las"). Experts more

Re: [R] Fwd: Error in setting the parameter values of k

Hello, I am sorry but after settings the value of C between 1 and 7, I get the following error message now: Error in self$assert(xs) : Assertion on 'xs' failed: The parameter 'C' can only be set if the following condition is met 'type {eps-svr, eps-bsvr}'. Instead the parameter value for

[R] A Labeling the median

After calling plot, I draw a horizontal line representing the median with aline. abline (h=median(walk_seconds), lty=1, lwd=2.0, col="firebrick4") Then, I want to label that line as the median and do so by calling mtext. mtext (side=4, "median", col="firebrick4", adj=“0.50”) The dilemma is I do

And if you have multiple labels, use lapply with bquote: plot(1:5, sin(101:105)^2, type="n") text(2:4, sin(102:104)^2, labels=lapply(102:104, function(i)bquote(sin(.(i))^2))) -Bill On Tue, Dec 29, 2020 at 8:31 AM Bert Gunter wrote: > Does this do what you want? > > plot(0:1, 0:1) > x <- .25 >

Thanks a lot, Milne and Patrick. I am going to change the values, hopefully the error message will disappear. Warm regards On Tue, Dec 29, 2020 at 5:53 PM Patrick (Malone Quantitative) < mal...@malonequantitative.com> wrote: > Likely, yes. Your error message says k must be at least 1, so

Re: [R] Fwd: Error in setting the parameter values of k

Likely, yes. Your error message says k must be at least 1, so searching below 1 is probably your issue. Also, logically, zero nearest neighbors doesn't seem to make a lot of sense. Pat On Tue, Dec 29, 2020 at 11:01 AM Neha gupta wrote: > Thank you for your response. > > Are you certain that

Re: [R] Fwd: Error in setting the parameter values of k

Thank you for your response. Are you certain that k = 0 is a legitimate setting? Since, the default value of k is 1, I wanted to search between the values of 0 to 3. Milne, Do you mean I have to provide both the lower and upper bounds greater than 1 in order to get rid of this error? On Tue,
