similar to: Shadowed Plot

  Dear R-help,   I have a longitudinal dataset with about 5,000 subjects. To avoid overly cluttered plot of the individual profile, I want the plot to be shadowed and to randomly select say 100 subjects which will be depicted using darker lines on the plot.   Kindly guide me through on how to do this in R.   regards John  [[alternative HTML version deleted]]

Hello, I am having a problem where code that plots lines using a different data frame plots bars with the current data frame (I am intended to plot lines). The code specifies lines (see below), so I can't figure out why the results are bars. I suspect that it may have something to do with the fact that in the data frame where the code worked as intended, the both variables specifying

Greetings, Is it possible to match several columns in a merge statement? Here is my problem: data1 looks like this... SUBID TARGID ITEM RATING 1 1 1 4 1 1 2 5 1 1 3 3 1 1 4 2 1 1 5 5 ...... SUBID is the ID for the raters, TARGID is the ID for the targets being rated, ITEM ranges from 1 to 64 crossed

I could do this in various hacky ways, but what's the right way? I have a nice application of the by function, which does what I want. The output looks like this: > auc_stress lab.samples.stress$subid: 2 cortisol amylase 1 919.05 6834.8 ---------------------------------------------------------------------------------------------------------------------------

Hi, May be this helps: funcName<- function(df1, x){ ?whatCol=df1[[x]] ?print("Got it") ?print(whatCol) ?} ? funcName(df,"ColA") #[1] "Got it" #[1] 1 2 3 4 5 ? funcName(df,"ColB") #[1] "Got it" #[1] A B C D E #Levels: A B C D E A.K. >I am trying to extract the 2nd column from a dataframe using a function called funcName. Note this is an

I have another question about drawing samples from a data frame. This might sound really tricky. Let me use a data frame I have posted earlier as an example: SubID CSE1 CSE2 CSE3 CSE4 WSE1 WSE2 WSE3 WSE4 1 6 5 6 2 6 2 2 4 2 6 4 7 2 6 6 2 3 3 5 5 5 5

Hi all, I have a large dataset that has >10k entries. The dataset is stored in a dataframe with the headers: SubID Condition1 Condition2 Result1 Result2 There are multiple entries for a given SubID(Subject ID). Condition 1 has 3 levels and condition2 has 2 levels (therefore there are 6 possible combinations all together e.g. Cond1 Level1 x Cond2 Level 1 etc.) and i need to compute for 1. The

I was running a sampling syntax based on a data frame (ago) of 160 rows and 25 columns. Below are the column names: > names(ago) [1] "SubID" "AGR1" "AGR2" "AGR3" "AGR4" "AGR5" "AGR6" "AGR7" "AGR8" [10] "AGR9" "AGR10" "WAGR1" "WAGR2"

Problema de autodidacta que no sabe cómo se llaman a las cosas, entonces no le sabe preguntar Google: Tengo una función que tiene que generar unos vectores, para después evaluarlos y devolverme el resultado; necesito que genere los nombres de los vectores y asignarles valores. Y No sé ni hacerlo ni decirlo con pocas palabras. a function(describir, segun.variable) { matriz <-

Hey, I am hoping someone can help me with a sampling question. I have a data frame of 8 variables (the first column is the subjects' id): SubID CSE1 CSE2 CSE3 CSE4 WSE1 WSE2 WSE3 WSE4 1 6 5 6 2 6 2 2 4 2 6 4 7 2 6 6 2 3 3 5 5 5 5 5 5

Dear R-users, I have written the following code to generate some trellis plots. It works perfectly fine except that it is quite slow when it is apply to my typical datasets (over several thousands of lines). I believe the problem comes from the loops I am using to subset my data.frame. I read in the archives that the tapply function is often more efficient than a loop in R. Unfortunately ,

Buenas, Alguno ha probado a usar Microsfot R Open? Segun leo, se han centrado en hacer que R por defecto sea multicore (cosa que podemos hacer usando parallel, foreach...) https://mran.revolutionanalytics.com/documents/rro/multithread Home [mran.revolutionanalytics.com]<https://mran.revolutionanalytics.com/documents/rro/multithread> This site uses cookies for analytics, personalized

Estimados apañeRos: La duda o propuesta que os voy a plantear es a la vez metodológica y relacionada con R. Me encuentro trabajando con tres variables que son el resultado de un computo de porcentajes. Me explico, se toma una muestra de n casos (unos 6.500 aprox) pertenecientes a i individuos (unos 230 aprox) en la que se comprueba si un determinado evento ha ocurrido o no, anotándose 1 en

Hola a todos! Estoy intentando crear un vector (alt) a partir de la repetición de valores provenientes de otro vector (altitud). A cada valor de altitud lo quiero repetir 1247 veces, y de ahi continuar con el siguiente valor de altitud. Probé varias cosas, pero esto me pareció lo más coherente: altitud=read.csv("C:/Users/IER/Dropbox/Pasantia Castelar/YungasLigustroTS/altitud44.csv")

Buen dia compañerxs de R, les traigo una pregunta bastante especifica. En el trabajo me estan requiriendo el uso de SQL, asi q estoy aprendiendo a usarlo desde R, con el paquete RODBC. Mi problema puntual es que al crear una tabla en el servidor SQL a partir de un data frame en R (usando la funcion sqlSave) no puedo definir el tipo de variables que quiero usar en el data frame. Segun entiendo

Buen dia Javier, muchas gracias por tu ayuda y el script compartido. Me va a servir como ayuda para seguir aprendiendo sobre RODBC pero no encuentro una solucion para este problema puntual de poder definir el tipo y ancho de las variables, q segun creo se hace con el argumento varTypes. Si alguien tien algun ejemplo donde haya usado la SqlSave y VarTypes, me sera de gran ayuda. Abrazo a todos
