Antes que nada puedes encontrar documentación sobre la librería ggplot2 que es la que yo uso para gráficos como el que quieres hacer, aunque hay otros paquetes que te pueden ser útiles: http://docs.ggplot2.org/current/ Adicionalmente a lo dicho por Carlos aquí te van otros ejemplos (los agrego porque no nos proporcionaste datos con lo que pudiéramos ver mejor lo que buscas):

Hola, escribo porque tengo una gran duda como gráficas tan fáciles en Excel son tan difíciles en R? No consigo hacer una gráfica en R de estas características. Osea como puedo dividir por sitios por tamaños. En una planilla enorme tengo la primera columna son las estaciones (pero solo quiero las tres ultimas) y después muchos parámetros, en las columnas 46, 53 y 60 los promedios ponderados. Y no

Hi I'm using fracdiff package to estimate the parameters of a fractionally-differenced ARIMA (p,d,q) model, and it works fine, but I wanted to have also the filtered series and the series of residuals. I understand these are calculated in the subroutine fdfilt, in the program fdcore.f, but I can't manage to get them out. Any suggestion would be much appreciated Thanks Susana Barbosa

Hi, I used function StructTS some time ago to fit a structural model to a time series. Now with R 1.6.2-1 I repeated the analysis with the same series and I get the following error: Error in KalmanLike2(y, Z, -1) : invalid argument type I tried with other series and I get the same error; I checked the examples in the documentation and they work fine. I suspect I am missing something

Dear Sirs, I would like to kindly ask for your assistance on the folllowing issue.

Hi all I am one recent user of R and have a few doubts I did a binomial GLM with 3 - factor and now I have to test contrasts to identify that treatments are different.

Hi, I have a function which takes some time to execute (20 sec.) and I want to show the progress of the execution with simple messages such as "10% done", "20% done", ... (with a simple "cat" function). The problem is that all the messages appear together when the execution of the function is over. How can I show each message at their corresponding time? Thanks,

This is a recurrent question but could not find the answer in the documentation. I want to build a dll for windows from a fortran program to be loaded with dyn.load. I can do it easily for linux with: g77 -shared -o foo.dll foo.f The g77 compiler (mingw-1.01) for windows does not recognise the -shared option. In windows the Writing extensions manual tells to use Rcmd SHLIB but I can't

Not for all users but for some. I'm using samba 3.0.20 running on Fedora Core 3. Security = ADS, winbind works and getent passwd returns local unix accounts plus the domain accounts as expected. It also returns a lot of entries like: 6811ff15281f4d19bdc:x:18004:10000:Anel Susana Esquivel:/export/private/6811ff15281f4d19bdc:"/sbin/nologin" I suspect these are accounts in a

Does anyone know if R have any problems with the exponential random number generation (function rexp)? I comment it because I executed data<-sort(rexp(100)) plot(data,dexp(data)/(1-pexp(data)),type="l") and the graphic isn't constant. (Note: exponential distribution have a constant hazard failure rate). Thank you, Juan

I''m sure I''m missing something rudimentary here... I seem to be having difficulty getting my favicon to appear. I have my favicon.ico in the public folder.

Dear R-listers, I have created a "dll" and I call it from a R function. However R stops and shows the message: "Unhandled exception in Rgui.exe (R.DLL): 0xC0000005: Access Violation" I get this error in other situations and I solved it verifying that all parameters are called fine. (e.g., double precision -> as.double, integer -> as.integer,...). I have verify this.

Just want to express MHO that the graphics produced by wmf.graph() in Splus 6 for Linux is only of barely acceptable quality (e.g., hallow circles were drawn too thick, making the plot look rather awkward).
