Two-way/Three-way sum.
Hi R Users,
I'm wondering how can I calculate two (or three) way sum of a variable. A
sample data is:
State Month Year Value
NC Jan 1996 1
NC Jan 1996 2
NC Feb 1997 2
NC Feb 1997 3
NC Mar 1998 3
NC Mar 1998 4
NY Jan 1996 4
NY Jan 1996 5
NY Feb 1997 5
NY Feb 1997 6
NY Mar 1998 6
NY Mar 1998 7
I'm trying to sum up "value" column by State*Month and by State*Month*Year.
Also, I may need to calculate mean value along with "sum".
Any help would be greatly appreciated,
Thanks,
Peng

how to calculate another vector based on the data from a combination of two factors
Hi,
I have a data set similar to the following
State Gender Quantity
TX Male 1
NY Female 2
TX Male 3
NY Female 4
I need to calculate cumulative sum of the quantity by State and Gender. The
expected output is
State Gender Quantity CumQuantity
TX Male 1 1
TX Male 3 4
NY Female 2 2
NY Female 4 6
I highly appreciate if someone can give me some hints on solving that in R.

Bert, it is working. However, If I want to chose to include only mos years

I define the years to get as follow.

lm and R-squared (newbie)
Hello,
I've two data.frames (data1 and data4), dec="." and sep=";".

When I do
plot(data1$nx,data1$ny, col="red")
points(data4$nx,data4$ny, col="blue")
, results seem very similar (at least to me) but the R-squared of
summary(lm(data1$ny ~ data1$nx))
and
summary(lm(data4$ny ~ data4$nx))
are very different (0.48 against 0.89).
Could someone explain me the reason?

New York Asterisk Users
This is an email to all New York based Asterisk users.
For some time it's been bugging me that we don't have a local contact
point/user community. If you are involved in Asterisk and in NY/NJ shoot
me an email, I'm going to try and revitalize either meetup.com or some
other shared environment for Asterisk users in NY.
Shoot me an email and once I get an idea of how many Asterisk users
there are in NY we'll work out what to do from there.
Cheers,
Dean

interp.surface() error (PR#7745)
...(a, loc) : subscript out of bounds
Since it is somewhat dependent on the data set, I cannot say exactly in
which cases these occur, but I believe I have found the problem and a
solution for it:
The scaling calculations in the code,
lx <- ((nx - 1) * (loc[, 1] - xa))/xr + 1
ly <- ((ny - 1) * (loc[, 2] - ya))/yr + 1
can lead to numerical error, so in the following lines
lx1 <- ifelse(lx == nx, nx - 1, trunc(lx))
ly1 <- ifelse(ly == ny, ny - 1, trunc(ly))
the equality statements which are the first arguments to the IF-ELSE
statements return false when they are suppo...

R computing speed
...at).
However, the computer (I have an Athlon XP 3200+ with 512 GB ram) takes
quite a while to estimate the model.
With 3 categories, 5 explanatory variables and roughly 5000 observations it
takes 2-3 min. For 10 categories and 10 explanatory variables (still 5000
obs) more than 1 hour.
Is there any way I can speed up this process? (Modifying the code or
modifying some R options maybe?)
I would be really grateful if anybody could help me with this issue, I
attach my code below.
Many thanks,

How to get a grid behind a boxplot

When I do a grid() after the boxplot
it overprints the boxplot:

if I try the panel.first

I can see the grid flash and go away.
