including NAs in a table
I have two factors, WC and WD. If I want a table including all the values
of each factor, including NAs, I can get a table by going:
table(as.character(WC),as.character(WD),exclude=c())
Is there an easier way?
I guess this is a feature request for table()
Thanks,
Robert.

data.frame: adding a column that is based on ranges of values in another column
Dear List,
I've been looking tirelessly for a solution to this dilemma but without success. Perhaps someone has an idea that will guide me in the right direction.
Suppose I have the following data.frame:
DF = data.frame(X = c(114.5508, 114.6468, 114.6596, 114.6957, 114.6828, 114.8903, 114.9519, 114.8842,
114.8579, 114.8489), Y = c(47.14094, 46.98874, 46.91235, 46.88265, 46.80584, 46.67022,

How to 'de-cross' a table?
Dear R users,
I have received a table in the following format:
id a b c1 c2 d1 d2
1 1 1 65 97 78 98
2 1 2 65 97 42 97
3 2 1 65 68 97 98
4 2 2 65 97 97 98
Factors of the design are: a, b, and e, where e has levels c and d. The
levels c and d then have 2 replicates (r) each.
Now I would like to get:
id a b e r value
1 1 1 c 1 65

How to count number of year per firm in panel data?
Hello,
I have an unbalanced panel dataset and would like to exclude all objects
that don't appear at least x times.
Therefore, I would like to include a column indicating for every line how
many periods are available, e.g.
id, year, number
1, 2000, 3
1, 2001, 3
1, 2002, 3
2, 2001, 1
3, ..., ...
This would allow me to exclude companies by setting "subset=number>=x".
However, I

using read.table, removing extra quotation mark from a text field? (e.g. ""cat" )
I am using read.table to import a text file within R.
There are several "errors" in my text file. An "extra" quotation mark has
inadvertently been included within a few text fields.
e.g. for a pipe (|) delimited text file, I have something similar to this:
1|7|30| "dog"
2|6|25| ""cat"
3|4|20|""
4|5| 56| "mouse"
5|3|56|

colnames from submatrix?
Hi R-Wizards:
I've looking through the R docs and have yet to find what I'm looking for
and have tried a few intermediate steps to now avail yet and rather than
spend another few hours looking for the solution, I figured I would post a
message.
I have a matrix (actually a set of them) that I want to pull all the names
of the non-zero columns into a vector/list for further processing:

NAs in unsplit factor
R-devel,
Below is a simple example calling split and unsplit on a numeric
vector of length 2 where 'f' is c(1,NA).
> unsplit(split(c(1,2), c(1,NA)), c(1,NA))
[1] 1 0
I noticed that the call to vector in unsplit gives us 0 as the 2nd
element of the result.
Is this the intended result, as opposed to NA?
Thanks for your help,
Jeff

Missing and number of days
Hi all,
Assume that I have a data set (“xcv”) with several variables and some of
the variables have a missing observation represented by -9 as shown below.
I want to exclude these observations from the analysis ( as a NA). Is
there a command that I can do it for the entire data set rather than one by
one for each variable ( tmp <- xcv[xcv$v1 != -9, ])

matrix manipulations
Hi,
I am having some difficulties with matrix operations. It is a little hard to explain it so please bear with me. I have a very large data set, large enough that it needs to be split in parts in order to deal with. I can work things on these "parts" but the problem lies in adding together these parts for the final answer.
So that been said, let's say that i split the data in 2

Rounding variables in a data frame
Hi All
I am trying to use the round function on some columns of a dataframe while
leaving others unchanged. I wish to specify those columns to leave
unchanged.
My attempt is below - here, I would like the column d3 to be left but
columns d1, d2 and d4 to be rounded to 0 decimal places. I would welcome any
suggestions for a nicer way of doing this.
d1= rnorm(10,10)
d2= rnorm(10,6)
