I want a data frame (derived from another data frame) of the form
Type Set
1 {1,5, 7}
2 {3,8)
..
tapply(Id,Type, set) works, but does not yield a data frame.
'set' is from package set/set6/etc
ddply does not seem to work with the function.
How should I proceed with t
Hi A,
I'm unable to work out what you are using as input. Maybe:
id<-data.frame(Type=c(1,2,1,1,2),set=c(1,3,5,7,8))
but that doesn't work with your
tapply(id,Type,set)
command. Perhaps a bit more detail?

Hello,
Sorry for the delayed reply and thanks for your feedback. I noticed this
problem both on Linux and on Windows.
Thanks for leading me to the solution.
I'm on R version 4.0.3 (2020-10-10) -- "Bunny-Wunnies Freak Out".
A common factor between the Windows and the Linux session is Emacs ESS.

Hello, Faheem:
1. You might get a better response if you "PLEASE do read the
posting guide http://www.R-project.org/posting-guide.html and provide

the bottom of each email in this list. That would make it easier for

The original data frame can be like
Type Id
1 1
1 5
1 7
2 3
2 8
..
tapply(Id,Type,set) will yield the sets correctly (assuming the data
frame is attached) but not a data frame of the form mentioned.
A similar ddply command does not work at all
HI All,
I am reading a data file which has different date formats. I wanted to
standardize to one format and used a library anytime but got
undesired results as shown below. It gave me year 2093 instead of 1993
library(anytime)
DFX<-read.table(text="name ddate
A 19-10-02
D 11/19/2006
F
df <- data.frame(X1 = c(1,1,1,2,2), X2 = c(1,5,7,3,8))
> df
X1 X2
1 1 1
2 1 5
3 1 7
4 2 3
5 2 8
> v <- with(df, tapply(X2, X1, c))
## v is a list, and I would work directly with this rather than converting
to a data.frame. But if you insist:
> df2 <- data.frame(v, row.names = names(v))
You have 4 " addFormats" commands. Maybe add one more?

Just a quick note: you can simplify my function and speed it up quite a
bit if speed is an issue. I had forgotten that the POSIXlt type could
act like a vector; using that you don't need those inner for loops, and
with a little calculation you can also do without the outer while loops.

Very helpful and thank you so much!

If I have a vector of site abbreviations and a vector of depths in those water
bodies, is there a simple way in R to combine them to make a third vector?
Examples:
sitedepth desired
MU 0 MU0
MU 1 MU1
MU 2 MU2
MC 0
desired <- paste(site,depth,sep="")

[1] "A1" "B2" "C3"
in your example
paste(site, depth, sep="")

See ?paste for other useful options.

Update:
The whole problem was due to set() from library sets.
'sets' is not a very consistent package, and users should be warned.
Set$new() and as.Set() from set6 work in a predictable, object-oriented way.
