Hola, Antes de nada, muchas gracias por tu ayuda. El código se ha acercado bastante, pero no termina de funcionar porque considera cada captura de un individuo como años consecutivos aunque haya pasado más tiempo entre ellos. Por ejemplo el individuo 4 es capturado por primera vez el año 1 y por segunda vez el año 3, por lo que debería de ser renombrado ya que en este ejemplo en concreto

Hola a todos, Quería preguntar si alguno sabe como puedo identificar registros con un mismo ID en el tiempo, pero que hacer referencia a objetos o individuos diferentes. En mi caso en particular estoy estudiando un animal que tiene una vida media cercana 2 años, y tengo una serie longitudinal de 25 años. El problema es que durante el muestreo en algunos casos durante la recoleccion de los datos,

Dear R community, I wish to ask a short question concerning factor-data in dataframes: When I subset the data and get rid of all data for one level, I still retain the level name (obtained by levels(dataframe$variablename) ). Is there a convenient way to get rid of the levels for which all data has been deleted? Thank you and wishing you an excellent day! Georg.

Dear R community, I am plotting a histogram and would wish to display another variable of the same dataset in a very narrow heatmap just below the x-axis. Never mind the specifics of my task: How can I draw a second graph/image just below a first graph/image? Thank you! Georg. *************** Georg Ehret JHU Baltimore, MD 21043, USA [[alternative HTML version deleted]]

Dear R community, I have a dataframe with say 100 different variables. I wish to regress variable 1 separately on every other variable (2-100) in a linear regression using lm. There must be an easy way to do this without loops, but I have difficulties figuring this out... Can you please help? Thank you and best regards, Georg. ***************************************** Georg Ehret Johns Hopkins

Hi, I have an R programming problem and I havent found anything in the documentation yet: I have a data matrix, in which two neighbouring columns represent replicates of the same experiment, e.g. something like this: A A B B C C row1 1 1 1 2 2 2 row2 1 1 1 1 1 2 I would like to test, if the values for the two replicates in a row are the same or if they differ and generate a new

Hello world, I am actually transferring a course in data management for students in biology, geography and agriculture from statistica to R - it works surprisingly well.

Dear R user group, I am working with boxplots and cannot solve the following problem: > data<-c(0,15,0,60,0,0,0,0,0,60,60,0,60,0,30,0) > data [1] 0 15 0 60 0 0 0 0 0 60 60 0 60 0 30 0 > boxplot(data) The boxplot has the first hinge and the mean-bar both at 0... Why is this the mean is clearly >0! Thanking you and wishing you an excellent day, Georg.

Dear R community, I am creating large graphs with hundreds of thousands of datapoints. My usual way for output was pdf, but now I am getting file sizes of >30Mb that do not open well (or at all) in Adobe. Is there a way to reduce the resolution or get rid of overlaying datapoints? Any other idea is also warmly welcome! Thank you and wishing you a good day! Georg. **********************

Dear Ms and Mr R, I am seeking a visually appealing presentation of 3 variables (~30 datapoints) that are correlated and that should to into the same direction. The objective is to show that they do go in the same direction and what differences there might be while also giving an idea of the values of the variables. I had done this with simple bargraphs for 6 datapoints in the past, but for
