Creating a new by variable in a dataframe
Hello,
I have a dataframe w/ 3 variables of interest: transaction,date(tdate) &
time(event_tim).
How could I create a 4th variable (last_trans) that would flag the last
transaction of the day for each day?
In SAS I use:
proc sort data=all6;
by tdate event_tim;
run;
/*Create last transaction flag per day*/
data all6;
set all6;
by tdate event_tim;
last_trans=last.tdate;
Thanks

removing specific rows from array
I'm attempting to create an array of treatment comparisons for modelling data generation. This involves comparison of one treatment (c2) with another (c3), relative to a common comparator (c1).
Attached code gives me the correct array but need to remove duplicates. Duplicates relate only to c2 and c3
such that I need to remove
r3 because c2 and c3 are same as r1 with c2 and c3 swapped

Conditional merging in R & if then statement
1)I am wandering how the following SQL statement can be written in R language
w/o using sqldf:
create table detail2 as
select a.*
from detail a,
pdetail b
where a.TDATE=b.TDATE
and (a.STIM >= b.STIM and a.STIM <=b.MAXTIM)
2) when try if then in R it only applies to the 1st row & not to whole
dataset like in SAS. How do you get round that?
in SAS:
data summary;
set all1;

Adding a new conditional column to a list of dataframes
Hi all ..,
I have a list of 7000 dataframes with similar column headers and I wanted to add a new column to each dataframe based on a certain condition which is the same for all dataframes.
When I extract one dataframe and apply my code it works very well as follows :-
First suppose this is my first dataframe in the list

Using lubridate to increment date by business days only
Hello,
I know how to increment a date by calendar date:
ticker$ldate <- ticker$tdate + days(5)
How do I increment it by business days only so that week-ends are not
counted?
So for example friday november 2 + 5days becomes friday november 9 & not
wednesday nov 7.
Thanks for your help.

Applying an R script to data within MySQL? How to?
I am trying something I haven't attempted before and the available
documentation doesn't quite answer my questions (at least in a way I can
understand). My usual course of action would be to extract my data from my
DB, do whatever manipulation is necessary, either manually or using a C++
program, and then import the data into R. Now I need to try to do it all
within R+RMySQL+MySQL.

Ok...so we need to do some more digging.
How did you install Solr? (I downloaded a "binary" installation and
unpacked it)
