similar to: Linear model with interaction

Hi all, I have a question about linear model with interaction: I created a data frame df like this: >df V1 V2 V3 V4 V5 1 6.414094 c t a g 2 6.117286 t a g t 3 5.756922 a g t g 4 6.090402 g t g t ... which holds the response in the first column and letters (a,c,g,t) in the other columns. I am interested to see if there are interactions between the neigbouring letters

Hola, Please, mira si esta vez funciona: #---------------------------------------------- ID <- c(1, 2, 3, 4, 5, 6, 7, 1, 2, 3, 8, 9, 10, 11, 12, 1, 2, 3, 4, 5, 6, 1, 2, 6, 8, 12, 7, 15, 16, 17, 18, 19, 20, 1, 21, 22, 19 ) Year <- c (1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6) df <- data.frame (ID, Year) df ID <- c(1,

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,

Hello! I am working on a statistical package called VOStat (http://vo.iucaa.ernet.in/~voi/VOStat.html) which uses a Java based GUI to input data and parameters from the user. Based on the inputs, an appropriate R script is generated and executed in the R console. As an example, consider the output to be a data frame. This data frame is printed in a well formatted way in the R console but the

Hello folks, I have a big project to work on and the dataset is classified so I am just going to use my own example so everyone can understand what I am targeting. Let's take Target as an example: We consider three brands of tape: Target brand, 3M and Avery. The original data frame has 4 columns: Year of Record, Product_Name(which contains three brands of tape), Sales, and Region. I want to

Responses should be copied to r-help using ReplyAll. You are still sending html formatted emails. If you are using Microsoft Outlook, click the Format Text tab and select ?Aa Plain Text?. No one has asked you to reveal the data set, only to create one with a similar structure. Is the data I sent reasonably close? What should it look like after it is transformed?

Hello I have 2 data frames df1 and df2. I would like to create a new data frame new_df which will contain only the common rows based on the first 2 columns (chrN and start). The column score in the new data frame should be replaced with a column containing the average score (average_score) from df1 and df2. df1= data.frame(chrN= c(“chr1”, “chr1”, “chr1”, “chr1”, “chr2”, “chr2”, “chr2”),

Hi, I have a data frame with 100 variables (numeric and non numeric types), and I want to join them in only one column, like a vector, but i want to keep the non numeric variables like they are. I know that i can do something like this: Suppose that my data is in df variable new_df<-data.frame(c(df[,1],df[,2],df[,3],df[,4],...........) This works but i have 100 variables! Any way of doing

No html!, Copy the list using Reply-All. The data frame group_PrivateLabel does not contain variables called Product_Name or Region.
