[R] Summarizing data containing data/time information (as factor)

Dear R user

I want to create a table (as below) to summarize the attached data
(Test.csv, which can be read into R by using 'read.csv(Test.csv,
header=F)'
), to indicate the day that there are any data available, e.g.value=1 if
there are any data available for that day, otherwise value=0.


              28/04     29/04    30/04    01/05   02/05
532703     0              1         1           1        0
532704     1              1         1           1        1
532705     0              0         1           1        0

Only Column A (Names: automatically stored as integer if being read into R)
and Column B (date/time: automatically stored as factor if being read into
R) are useful for this task.

Could anyone kindly provide me some hints/ideas about how to write some
code to to this job please?


Many thanks in advance!

Unfortunately you did not read theinformation about posting attachments
carefully enough and you csv filewas scrubbed by the mailserver.. I will attempt
to recreate it:> dat <- read.table(text="             28/04     29/04    30/04   
01/05   02/05+ 532703     0              1         1           1        0
+ 532704     1              1         1           1        1
+ 532705     0              0         1           1        0",
header=TRUE)> sdat <- stack(dat)
> sdat$id <- rownames(dat)
> sdat2 <- sdat[sdat$values>0, c(3,2,1)]
> sdat2$ind <- factor( sub("\\.", "/", sdat2$ind))
> sdat2$ind <- factor( sub("X", "", sdat2$ind))
At this point I think I have something similar to your original and will show
how xtabs() can be used:
> xtabs(values ~id+ind, data=sdat2)        ind
id       01/05 02/05 28/04 29/04 30/04
  532703     1     0     0     1     1
  532704     1     1     1     1     1
  532705     1     0     0     0     1

The dates are not sorted the same but if you used Date formatted values, they
might.
> sdat2$dt <- as.Date( sdat2$ind, format="%d/%m")
> xtabs(values ~id+dt, data=sdat2)        dt
id       2012-04-28 2012-04-29 2012-04-30 2012-05-01 2012-05-02
  532703          0          1          1          1          0
  532704          1          1          1          1          1
  532705          0          0          1          1          0

[R] Summarizing data containing data/time information (as factor)

HI HJ,
No problem.


The gsub() was used to just format your date column to make almost the way you
wanted the results:
dat2$date
# [1] "2012-04-29" "2012-04-30" "2012-05-01"
"2012-04-28" "2012-04-29"
?#[6] "2012-04-30" "2012-05-01" "2012-05-02"
"2012-04-30" "2012-05-01"



gsub(".*-(.*)-(.*)","\\2/\\1",dat2$date)
?#[1] "29/04" "30/04" "01/05" "28/04"
"29/04" "30/04" "01/05" "02/05"
"30/04"
#[10] "01/05"


#Suppose I just reverse the contents inside the second " ".
gsub(".*-(.*)-(.*)","\\1/\\2",dat2$date)
?#[1] "04/29" "04/30" "05/01" "04/28"
"04/29" "04/30" "05/01" "05/02"
"04/30"
#[10] "05/01"
#From the p.s., I guess you understand the difference.

#The contents inside the first " " are the pattern we match, and the
second " " are the replacement.?

#Now, the ".*-(.*)-(.*)" -first .* will match all the contents before
"-" in dat2$date.? I used brackets (.*) for the second and third so
that it could be select those specifically and use it #as replacement \\1 and
\\2 inside the second " ".


#If you want to learn regular expressions, there are a lot of resources on the
net.
#For example:
http://www.regular-expressions.info/

Wow! Thanks so much Arun!!?

I like this piece of code very much, ?especially using 'aggregate()' to
solve my problem. ?Marvellous!

The code does what I wanted perfectly. ?May I just ask how the ?gsub() bit
works, e.g. now I understand it replace the pattern in the first part, and
`(.*)` groups everything between the two '-' in my date/time data, but I
did not get how the second part works (e.g. '\\2/\\1')?? ?I think this
gsub() and grep() are very useful for coding, so?if there is a good source
(better than using help(grub)) ?to learn them that can be recommended that would
be very much grateful. ?

Massive thanks again!

p.s. I just learned using as.Date and mended the following code to make the
table in?Chronological order as I originally wanted,?
e.g. ?'?28/04 ?29/04 ?30/04 ?01/05 02/05'? rather than ?'01/05 02/05
28/04 29/04 30/04'

dat2$date1<-as.Date(gsub(".*-(.*)-(.*)","\\2/\\1",dat2$date),format="%d/%m")

[R] Summarizing data containing data/time information (as factor)

Dear Arun and David

For the same dataset I sent in my previous email (I am attaching my
data 'Data20120918.tex' as txt file this time as required),  how could I
create a subset only contains data  collected between 29/04/2012  12:00 --
01/05/2012 12:00, where the time format in the date/time column is
'dd/mm/yyyy hh:mm'?

Many thanks again in advance!

HJ
p.s. in this case I'm not too sure whether I should open a new question or
just do a reply like this one, as I was thinking this question needs
relevant knowledge to the question in my previous email...?
