Hola miembros de la lista, Estoy buscando una manera de elaborar tareas o examenes interactivos para mis clases de estadística con R. He visto 2 paquetes muy interesantes que son, learnr y gradethis, pero todavía no logro entender completamente su dinámica. Por lo que entiendo, en gradethis si el estudiante se equivoca tiene la posibilidad de reintentar hasta dar con la solución, lo cual no lo

Muchas gracias Emilio. Sí, yo cometí un error, veo exams puede usar Rmarkdown también. Manuel El dom., 29 mar. 2020 a las 9:11, Emilio L.

Hi, all, I am currently trying to learn this example. http://learnr.wordpress.com/2009/03/17/ggplot2-barplots/ I created the stack bar easily. If I would like to rank the stack bar from the highest on the right, shortest on the left and eventually I could show the data "1991-00" on the left and "1823-30" on the right, how could I do that? Apart from this, I find

I'm trying to reproduce the 3rd graph on the page of this site: http://learnr.wordpress.com/2009/03/17/ggplot2-barplots/ . However, the data below produces a ggplot with the stacks sorted in alphabetical order from the bottom up. I'd like the stacks to be in the order "Europe", "Asia", "Americas, "Africa", "Oceania". Is there an easy way to

I am using R 2.11.1 in a Microsoft Windows 7 environment.   I tried using WriteXLS, but get the message " In system(cmd) : perl not found"   What is the "easiest" way to write an R dataframe to Excel?  (I am familiar with WriteXLS, but I do not have PERL installed, and if not needed, do not wish to install it.)   I am also familiar with write.table, but if possible, wish to

Buenos días: A ver si alguien me puede iluminar, porque ya he sobrepasado los límites de mi paciencia y de mi imaginación con este asunto: Dado un gráfico creado con un plot (y funciones auxiliares como polygon, etc.) y una tabla creada debajo de ese gráfico (creada con addtable2plot), y dados unos text situados a modo de título encima del plot y otros encima de la tabla, ¿por qué cuando trato

Hi, I have a question related to the newest version of ggplot2 (0.9.0). I just updated this morning and from CRAN it looks like the Mac version is the only one at 0.9.0 as of right now. http://cran.r-project.org/web/packages/ggplot2/index.html Anyway, I was in the midst of a project where I was trying to replicate "Back-to-back Bar Charts" in this blog post.

Hi there, I'm having trouble working out how to change the colors of polygon shading lines. If I plot a polygon with polygon(poly,density=30,borders=gray(0.5)) I get gray borders but black shading lines; I have tried adding col=gray(0.5), bg=gray(0.5) and fg=gray(0.5), but no luck. How can I change the colors of the shading? The help file doesn't seem to detail this, so any

Hello again With the poylgon function it's possible to plot shaded areas under a curve. But somehow it connects the start and the endpoint of a line and fills whats between them. I would actually like to set the boarders of the shading by two min and max curves, but I failed. i tried stl like: polygon(min, max, border=0), where min and max are my curves plotet by plot(max) lines(min)

Hello all , I am beginner and new to this -R world. I have heard much about R and started working on it. I have some data of 20 business applications( y -axis) and Months( x-axis) and values as their score for every month . I tried to generate a heatmap with this data and got some good results. Can some one help me on how to generate the legend next to heatmap please... can some one send me

How do I reverse the order of the legend in a bar plot to match order of the x-axis? In other words, I want the stacked colors of the legend to match the stacked colors of the bar plot. I tried this, but it didn't work. colors <- c("5" = "red","4" = "blue","3" = "darkgreen") p <- qplot(factor(cyl), data=mtcars,

I have three plots and I want the *plot area* to be of the same width on each plot. Since the three plots have different legends, the text width of the legend affects the width of the plot area (longer legend text = narrower plot area). Exporting the three figures to postscript device of same size gives thus unequal plot areas. How can I calculate the correct width of postscript device for each

Basially I have the observation for x, y, and z for each fixed z, the value of y moves from 0 to y0 as x moves from 0 to x0. I then move the curve for z from 0 to z0 and form a continuous surface. want to know if there is a way that R can replace my handdrawing. -------------- next part -------------- A non-text attachment was scrubbed...

I would like to learn AsciiDoc. Is there any good examples how to use AsciiDoc with R? I know that there is packages called ascii to do this, but it would be nice to see some examples how AsciiDoc works with R. Is there an AsciiDoc distribution for Max OS X? -Johannes

Forum, I have two time series that I plot up using the data/code below. The x-axis shows weekly time step starting on 6/3/1999 (SP=10) and ending on 10/25/2007 (SP=448). I'm trying to shade between the two lines in a similar fashion as the graph found here: http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=122 Can the polygon function be used to do this? There are lots of
