Re: [R] label in scatter3d plot

See what scatterplot3d() return. This is rather helpful, i.e. try s3d <- scatterplot3d(x,y,z, main="3D Scatterplot") text(s3d$xyz.convert(x,y,z)$x, s3d$xyz.convert(x,y,z)$y, V4, pos=4, cex=0.7) Well, you still don't see too much, but at least it does what you were asking for. Best, Uwe Ligges

[R] Simplifying an expression with an integral

Dear R experts, I am computing the following integral. [image: \int_{1,100} \frac{1}{x+Max(x-50,0)} g(x)dx], where g is the density of the standard normal, and [1,100] is the domain. 1) I use the following code which works fine: integrand1<- function(x){1/x*dnorm(x)} integrand2<- function(x){1/(2

Once you start describing your code in language that indicates you have read some of the recommended materials, we can make some progress. For example, you are still posting in HTML format so your code is getting mangled (see Posting Guide). You don't seem to understand what tryCatch does (see ?
