combine the data frames into comma separated list.
Hi R users,
I am new to R and am trying to merge data frames in the following way.
Suppose I have n data frames each with two fields. Field 1 is common among
data frames but may have different entries. Field 2 is different.
Data frame 1:
Src Target1
1 aaa
1 bbb
1 ccc
2 aaa
3 ddd
Data frame 2:
Src Target2
2 aaaa
3 dddd
4 bbbb

read.table : fill missing entry with "unAvailable" [edit]
Hi R users,
I try to read a data file (tab delimited format) in which some of the
entries in a particular field are missing. Is it possible to fill the
unavailable data with 'UnAvailable' string while performing read.table()
Something like
df = read.table(DataFile, header=FALSE, fill_missing_entry = 'unAvailable')

cbind alternate
I have two one dimensional list of elements and want to perform cbind and
then write into a file. The number of entries are more than a million in
both lists. R is taking a lot of time performing this operation.
Is there any alternate way to perform cbind?
x = table1[1:1000000,1]
y = table2[1:1000000,5]
z = cbind(x,y) //hanging the machine
write.table(z,'out.txt)

download.file
I am downloading say 100 files from ucsc website and storing it into dest
folder.
download.file function create a file in destination folder even if the file
is not present which is something I dont want.
So I wrote if condition to remove the file if the download function has non
zero value.
Now it exits when there is an error or file not present. How can I use
"try" and "if"

mode of frequency distribution table
In a frequency distribution table (bell shaped), how can we find the most
frequent range?
for example:
x = c(1,2, 4,4,4,4, 5,5,5,6,6,5,5,5,5,5,6,6,6,13, 17,17,30,100,300)
barplot(table(x))
In the code above, which function do we use to find that the most
frequent value range from 4 to 6.
Thanks.

[Resolved] combine the data frames into comma separated list.
Hi
Thanks Gabor for your suggestion. I am posting the code that worked for me.
dataframe1 = data.frame(cbind(Src = c(1,1,1,2,3), Target1 =
c('aaa','bbb','ccc','aaa','ddd'))); #must be data frame
dataframe2 = data.frame(cbind(Src = c(2,3,4,4,4), Target2 =

Can't install.packages() from local repo in 2.15.2
Hi guys
I think there's a high chance this is a bug. But I can't rule out that I can be blamed for this. I've posted this to bugzilla (#15092). Then I read that I probably should have posted it to R-develop first. Sorry for doing this in the wrong order.
I've set up a local repo on my local drive (happens to be mapped to L:/). It has the following structure (as per

why is \alias{anRpackage} not mandatory?
Dear R developers,
if one uses package.skeleton() to create a new package, then a file
anRpackage.Rd with the following entries is prepared:
\name{anRpackage-package}
\alias{anRpackage-package}
\alias{anRpackage}
\docType{package}
Packages created this way have a definite entry or overview page, so:
?anRpackage
gives new users of a certain package a pointer where to start reading.

S4 objects in the data directory
Hi
[R-2.10.0; suse linux]
I am having difficulty creating S4 objects in the data directory of a
package. I want
to create a bunch of simple S4 objects for use in the examples section
of the Rd files.
It says in R-exts that:
" R code should be ?self-sufficient? and not make use of extra
functionality provided by the package, so that the data file can also be
used without having to load

Class not found when search in .onLoad
Hi,
I am facing with a strange behaviour of isClass and extends when these
are called in .onLoad in both R 2.12.1 and R 2.13.0. This is preventing
my package from doing some object initializations at a proper place
(i.e. in .onLoad).
Suppose one defines two S4 classes in a package, and that one needs to
check the inheritance between these two when loading the package (e.g.

Possible Regression in setClassUnion between 3.5.0 and 3.6.0
I am trying to create a class union of class unions to facilitate method
dispatch. When I execute code in the global environment, everything acts as
expected, however when I put the same code in the context of a package,
selectMethod can no longer find the correct method. This first block below
puts the code in the context of a package:
