...ble to use expressions, and I am able to use paste to put text and values of variables into plots. But the two things just won't work together. Here is some example code that shows what I mean. plot(NA,xlim=c(0,100),ylim=c(0,100)) #show plot math works text(16, 22, expression(slope == frac(partialdiff * f(hat(theta)), partialdiff * hat(theta)))) # I want to put values of variables into the middle of expressions avar1 <- 10 # prove I am able to use paste! text(40,40, paste("a word",avar1,"other words") # But I'm completely frustrated by the problem of making pa...

Dear R Helpers: I am trying to annotate a plot. The following code snippet works, but it is kind of a kludge since it adds the partial derivative symbols after creating the plotmath frac(). Is there a more elegant way to write a partial derivative? dev.off() plot(NA, xlim=c(-3,3), ylim=c(0,1.6), xlab="", ylab="", tck=-0.015) text(1.6, 1, expression(paste("slope =

Dear R-users, I would like to calculate elasticities and sensitivities of each parameters involved in the following transition matrix: A <- matrix(c( sigma*s0*f1, sigma*s0*f2, s, v ), nrow=2, byrow=TRUE,dimnames=list(stage,stage)) The command "eigen.analysis" avaliable in package "popbio" provides sensibility matrix and elasticity matrix

I want to write something like (LaTeX style) b_{norm}=\frac{F\prime(0)}{R\prime(0)} how do I add the "prime" (first derivative) to a R-plot? The help of "plotmath" just talks about "partialdiff". Can you complete this command? text( 30,0.05,labels=expression(b[plain("norm")]==frac(F(0),R(0))) ) Thanks, Thomas

Hello, I am trying to get a time derivative on a plot title. I prefer to have it in the form \dot{s_i}, but \partial s_i/\partial t would be O.K. In the graphics demo I cannot find either a dot or a partial equivalent.

...art of the NEWS file: CHANGES IN R VERSION 1.5.1 NEW FEATURES o Enhancements to mathematical annotation of plots: - expressions involving dot(<something>) now produce a dot accent above the <something> (initial patch from Ben Bolker). - within an expression, the symbol partialdiff is now converted to a partial differential symbol (greek delta). o smooth.spline() has a new argument `nknots' allowing to set the default number of knots (when `all.knots = FALSE' as per default).
