Strange behaviour of as.Date function
Dear All,
I'm happily extracting data of temperature from an oracle db
under R via RODBC. After manipulating the extracted data I put them
into a data.frame 'dati' which is as follows:

reshape question
I am a relative R newbie and I am having trouble with reshape() on R
V1.9.1 on Linux. The same code appears to be ok when run on R V2.2.0 on
Windows and a V2.1 on Linux. Any help would be great as I need to stay
on V1.9 for the immediate future... Thanks, Reid Hutchins

reshape direction=wide
Hello
I am reshaping a data.frame bids --> reshaped as shown below.
I thought this should be possible with a single invocation of
reshape, but the only way I came up with is reshaping subsets for each
keyword and then joining them together. Does anyone have an idea how to
solve this in a more elegant way? Efficiency is a concern as the datasets
are very large.
Is there a way to specify

Problem using reshape with missing values in idvar
Hello everybody,
I have been recently using reshape to convert "long" data to "wide"
data. Everything was going well until I reached some problematic
datasets. It has taken me a couple of weeks to finally figure out
what might be happening.
The problem is reproducible with test cases, and on two versions of R
(Windows 2.2.0 and x86-64 Fedora Core 3 R 2.2.0).

reshape "Error in data[, timevar] : incorrect number of dimensions"
I have two waves of a survey given to students at various middle
schools and high schools, with student id numbers for each student. I
am having difficulty reshaping the file from long to wide.
My code is below:

Hi,
It's probably a simple issue but I'm struggling with that. I'll use the
example shown in the help page.

wide <- reshape(Indometh, v.names="conc", idvar="Subject",
timevar="time", direction="wide")
head(wide)

reshape without timevar argument?
Hi
I have a data.frame with 2 columns. The first column is an ID column.
The other columns are description of the ids. There is more than one
description for each Id.
Want I want to get as a value is a data.frame where each row
corresponds to one ID and has as many columns as different
descriptions.
I have used a very convoluted step, but I'm very convinced there is
an easier way to do

reshape (was: Comparing rows in a dataframe)
Hi all:
I solved the previous stated problem in something of a brute force way
(but it works). I seem to now be running into one little hiccup using
reshape. Here is a quick snip of the data in long format:

7 Grade 4 3 2002 100005

Trouble reshaping some data
I would appreciate some advice on the following task. I have
some data that currently looks like this:
t1 <- data.frame(id=c(1,1,2,2),

I'd like it to look like this:

'sep' argument in reshape()
I wonder if the 'sep' argument in reshape() is being ignored
unintentionally:
## From example(reshape)
df <- data.frame(id=rep(1:4,rep(2,4)),
visit=I(rep(c("Before","After"),4)),
x=rnorm(4), y=runif(4))
reshape(df, timevar="visit", idvar="id", direction="wide", sep = "_")

question about reshape
Hello everyone,
I have a bit of a problem with reshape function in R.
I have simulated some normal data, which I have saved in 4 vectors.
y.1,y.2,y.3,y.4 which I combined a dataset:
dataset<cbind(y1,y2,y3,y4). I have also generated some subject id number,
and denoted that by subject.
So, my dataset looks like this:
subject y.1 y.2 y.3 y.4

Making a markov transition matrix - more progress
I solved the problem in one more (and more elegant) way. So here's the
program again.
Where does R stand on the Anderson-Goodman test of 1957? I hunted
around and nobody seems to be doing this in R. Is it that there has
been much progress after 1957 and nobody uses it anymore?

Reshaping data from long to wide without a "timevar"
Hello All,
I was wondering if it's possible to reshape data from long to wide in R without using a "timevar". I've pasted some sample data below along with some code. The data are sorted by Subject and Drug. I want to transpose the Drug variable into multiple columns in alphabetical order.
My data have a variable called "RowNo" that functions almost like a
