Hello: I am working on getting some statistics related to clinical trials and stuff. I have to work with ICD9 codes. Is anyone aware of any R method that deals with ICD9 codes verification and manipulation. Thanks Vishwanath

Can any one help it will be very kind, loop statements I have this table and some more records, I want to reshape it V1 V2 V3 V4 V5 V6 V7 V8 V9 V10 TP53 Dis1 Dis2 Dis3 Dis4 Dis5 Dis6 DCI New1 New2 New3 New4 FDI Hi2 H3 H4 GHD I1 I3 I4 I5 I6 I7 I8 I want my new table or matrix to be some thing like this V1 V2 V3 Tp53 Dis1 Dis2 Tp53 Dis1 Dis3 Tp53 Dis1 Dis4 Tp53 Dis1 Dis5 Tp53 Dis1 Dis6 Tp53 Dis2

Hello. I am looking for a function that will allow me to paste rows together without regard for the numbers of columns in the datasets to be joined. The only columns where it matters if they are aligned correctly are at the beginning - the rest of the columns represent differing numbers of ICD9 (disease) codes reported by each person(record) at a health visit. They are in no particular order.

Hi all, I'm using the medical risk package to determine the risk stratification Index based on the ICD9 codes. Although, I have been successful in using it, I'm unable to interpret the output. here is the sample code # Calculate RSI for each patient ("id") in dataframe cases <- data.frame(id=c(1,1,1,2,2,2,2,2), +

I have a list of ICD9 (disease) codes with various formats - 3 digit, 4 digit, 5 digit. The first three digits of these codes are what I am most interested in. I would like to either add zeros to the 3 and 4 digit codes to make them 5 digit codes or add decimal points to put them all in the format ###.##. I did not see a function that allows me to do this in the formatting command. This seems

For some reason when I apply a function to a single row in R it works, but when that same row is in a data.frame it does not, see below: apply(dx[954,], 1, query.db) 2571 1092 0.06044147 3890 0.05948577 3273 0.05911261 794 0.05855583 4241 0.05854064 3560 0.05602690 apply(dx[954:955,], 1, query.db) $`2571` numeric(0) $`1194` 908 3754 5119 2835

Perdon por no se lo suficientemente claro :( Tu codigo produce `validPairs` que tiene 7 variables y 360 observaciones. Donde > validPairs[1,] V1 V2 V3 V4 V5 V6 valid 60 e1 g1 c1 e1 g1 c2 Valid indica que un maestro tiene asignado c1 y c2 en la escuela e1 y el grado g1. Correcto? Si es asi, esto es casi lo que queira producir y creo que puedo llegar a donde quiero usando tu codigo de base.

Gracias Carlos, Tu codigo es un gran paso en el sentido correcto pero no produce exactamente lo que estoy buscando. Mi "solucion" en stackoverflow <http://stackoverflow.com/questions/31137940/randomly-assign-teachers-to-classrooms-imposing-restrictions/31143808#31143808> produce un data frame `schoolGrade` con 240 observaciones y 7 variables. Mi objetivo es poder generar un data

Hola, 0. La falta de 'elegancia' hace que sea mas dificil hacer cambios al codigo. Por ejemplo cambiar n.classrooms <- 4 a n.classrooms <- 20 1. Cuando tengo solo 4 puedo hacer esto: schoolGrade$A <- Teachers$Teacher.ID[1:cuttoff1] schoolGrade$B <- Teachers$Teacher.ID[1:cuttoff1] schoolGrade$C <- Teachers$Teacher.ID[(cuttoff1+1):n.teachers] schoolGrade$D <-

Hi, I've had a quick look through the package list, and unless I've missed something, I can't seem to find anything that will do I-MR / Xbar-R / Xbar-S control charts ? Assuming there is something out there, can anyone point me in the right direction ? Thanks ! TIm

Hello, I have no experience with I-MR charts but a google search found package qcc. Maybe it's what you're looking for.
