R-help group, I'm looking for some assistance on using an R-script to read STDIN from hadoop. Example, say I have two tables. One is a student table, the other is a class roster table (tables join on student_id). Student SAT score is in the student table, whether the student passed or not is in the roster table. So to determine if a student passed or failed based on their SAT score, I'd

Hello All, I've been reading books about R for awhile now and am in the process of replicating the SAS analyses from an old report. I want to be sure that I can do all the things I need to in R before using it in my daily work. So far, I've managed to read in all my data and have done some data manipulation. I'm having trouble with fixing an error in a date variable though, and was

Dear R Helpers, I am having difficulty with strptime. I wish to find the differences between two vectors of times. I have apparently no difficulty to convert the vectors to the appropriate format using strptime. But, then difftime does not calculate all the differences. Here is the code and output:- dob=strptime(as.character(datx$BDT),'%d-%b-%y'); dob$year=dob$year-100

Got a weird situation with an update put to a controller with a form with nested attributes. On the data below, I am updating data for both items (''0'' and ''1'') in rosters_attributes (in the example below I am updating the ''name'' attribute to a new value in both cases. What I am stuck on is that ''1'' gets its data updated,

Hi, I wanted to calculate the age of people in my dataset by subtracting the individual's date of birth from their intake into a program. After several hours, searches of help archives, and the downloading of lubiridate, I have had no luck with this. Below is the code I used. > intakeDS$DOB <- as.character(intakeDS$DOB) > intakeDS$DOB <- as.Date(intakeDS$DOB,

Hi, I wrote a little helper that calulates someone''s age based on his/her date of birth. def age(dob) diff = Date.today - dob age = (diff / 365.25).floor age.to_s end It works fine, but it''s not completely accurate as it just takes the average days in a year. It should be able to calculate this more accurately, right? I can''t work it out

Hello, I have a data which looks like below: Some of the patients have multiple diagnosis.

Hello, I am trying to read a database exported from SAS. It is form of csv, and the date format reads '02-Feb-99'. I used following code to convert character to date format, db$dob<-as.Date(db$dob, format="%d-%b-%y"). but it doesn't work, only seems NA. What's wrong with this code? Thank you in advance.

Is there any easy way to pull out the row indexes for a logical matching statment? #################example code######################################### foo <- data.frame(name=c(rep("A", 25), rep("B", 25), rep("C", 25), rep("A", 25)), stuff=rnorm(100), and=rnorm(100), things=rnorm(100)) #this is what I want but I would like the row indexes

Hello, I have some data that has dates in the form 27.02.37. I convert them to a date object as follows: as.Date(data$date,format="%d.%m.%y") But this gives me years such as 2037 when I would like them to be 1937. I thought of trying to take off some time i.e. as.Date(camCD$DoB,format="%d.%m.%y") - 100*365 But that doesn't seem to work out correctly. Any ideas how to

I have files which have columns of data that look like this: DOB 9/27/1964 ... That is, dates in month/day/year format. When variables like DOB are read in, they are converted to factors. So, I wrote this to convert from date to age in years: age<-function(x) {as.numeric(Sys.time()-strptime(as.character(x),format="%m/%d/%Y"))/365.25} This isn't very precise or pretty, but it
