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 though.. Jeroen

...n 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 hoping someone could help. One of the patients in my data has a DOB incorrectly entered as: '11/23/21931' Their DOB should be: '11/23/1931' How can I correct this problem before calculating age in the code below? DOB starts out as a factor in the Demo dataframe but then is converted into a date. So I had thought the ifelse that follows could be...

i know it''s probably really simple, how do i work out someone''s age if i have their d.o.b. stored as a date in my db. cheers -- Posted via http://www.ruby-forum.com/.

...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$year-100 sdate=strptime(as.character(datx$SDT),'%d-%b-%y') head(dob); head(sdate) [1] "1922-07-14" "1922-07-14" "1922-07-14" "1922-07-14" "1921-03-23" "1921-03-23" [...

I cobbled this together based on a few previous posts and some tinkering, nothing fancy (my first bit of Ruby infact) but it seams to work for my purposes. My questions is actually why can I call <%= h(child.age(child.dob)) %> in a view but not <%= h(child.age_year_month(child.dob)) %>? Both work fine in the console. Thanks for any insight, Hugh child.rb class Child < Person end person.rb class Person < ActiveRecord::Base def age(dob) unless dob.nil? years = Date.today.year - dob.yea...

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, "%Y%m%d") > > # Make IntakeDate a date variable, by first converting it from numeric to character then from character to date > #intakeDS$IntakeDate <- as.character(intakeDS$IntakeDate) > in...

Hi, I have a column of DOB in mm/dd/yyyy. I want to convert this format to age. Thanks a lot.   Best,Farnoosh Sheikhi [[alternative HTML version deleted]]

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 do this?

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.

Hi, I''ve put together a simple form that contains among other things a date_select: <%= date_select(:user, :dob, :order => [:day, :month, :year], :start_year => 1900, :end_year => Date.today.year) %> In my controller I have some code to create a user entity from the parameters posted up from the form, like so: parameters: {"user"=>{"dob(1i)"=>"2006", "do...

...rginal data is in SAS format. 3 columns of this dataset are supposed to be dates, but read.xport doesn't recognise them as dates (all columns are read in as mode numeric). So I load up the date library and go ahead to convert the 3 columns into dates. So doing ... > library(date) > s05962$DOB_as.date(s05962$DOB) > s05962$DOB # to check if everything is ok, and it is...dates have been correctly converted...

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...

...not in a standard unambiguous format ? In the former case, one could easily lose the date rather than recognizing it is in error and needs to be corrected. ? So my question is how best to check these sorts of date values. ? So far, I've been checking date values with things like: ? sort( unique(DOB) ) sort( unique(substr(DOB, 1, 4) ) ) sort( unique(substr(DOB, 6, 7) ) ) sort( unique(substr(DOB, 9, 10) ) ) ? These are good for seeing, say, year values that are clearly in error, but don't do much to catch the impossible date I cited above. ? How can I use R to better scrutinize my date data...

I had occasion recently to read in a one-line *.csv file that looked like: "CandidateName","NSN","Ethnicity","dob","gender" "Smith, Mary Jane",111222333,"E","2/25/1989","F" That "F" (for female) in the last field got transformed to FALSE. Apparently read.csv (and hence read.table) are inferring that if the entries of a file are all F's and...
