Dear All For my calculations, I am needing to use more floating-point precision than the default one of R. Is that possible? And, if yes, how? Thanks in advance, Paul

> Is there an R function to generate random integers? Thanks in advance. For example, if you want 5 random integers from the sequence 1:50, you can do the following: sample(1:50,5) Paul

Dear All, Can R produce dot plots like the one of the following picture: http://en.wikipedia.org/wiki/Image:Dotplot_of_random_values.png ? I have tried dotchart, but no success. Thanks in advance, Paul

Dear All, How to test whether the correlation in the matrix of correlation of a two-equations SUR model fitted by package systemfit are significant? Thanks in advance, Paul

Dear All, I tried to download the package Rdonlp2 from the address given at "CRAN Task View: Optimization and Mathematical Programming": http://arumat.net/Rdonlp2/ However, this link seems to be dead. Any ideas? Thanks in advance, Paul

Dear All, I would like to export, as a pdf file, a plot with the LaTeX font lmodern as the font of my graph. Could somebody please help me? Thanks in advance, Paul

Dear All I would like to know whether it is possible with R to get the mathematical expression of the density of a sum of two independent continuous random variables. Thanks in advance, Paul

Dear All, With plot, one can use to the option 'axes=F' to remove axes. I have tried it with stripchart, but no success. How can one then customize the x-axis with stripchart? Thanks in advance, Paul

Dear All, Consider the following code: plot(0,0) text(0,0.5,expression(italic(theta))) I would like to get theta in italic, but I always get it upright. Any suggestions? Thanks in advance, Paul

Dear All, The function curve() draws the graph of functions from R to R. Is there some homologous function to curve() to draw functions from R^2 to R? Thanks in advance, Paul

Dear All I would like to know whether it is possible with R to define a discrete random variable different from the ones already defined inside R and generate random numbers from that user-defined distribution. Thanks in advance, Paul

Dear All I would like to draw a picture with the density curve of a normal distribution over a histogram of a set of random numbers extracted from the same normal distribution. Is that possible? Thanks in advance, Paul

Dear All, Is there some way of drawing a boxplot, with R, when one does not have the original continuous data, but only the data grouped in classes? The function boxplot() can only deal with original data. Thanks in advance...

Dear All, The package mratios can perform inferences for ratios of normal means. Is there some other package to do the same but with non-normal populations. Since I have got large samples, an asymptotic procedure would be fine. Thanks...

Dear All, I have just installed R 4.1 and RStudio on Fedora Toolbox. Everything went fine, but when I try to run RStudio, it opens as a white window flickering permanently, and does not progress from that. Any ideas...
