Dear list,
I would like to download all the webpages of the Journal Citations
Report (science edition), for a given year. I can do so manually, but
that it very time intensive, so I would like to use R for that.
I have tried many things, including:

Witold,
Here's one way:
Vec <- rnorm(30)
Vec.cut <- cut(Vec, breaks=c(quantile(Vec, probs = seq(0, 1, by = 0.20))),
labels=c("0-20","20-40","40-60","60-80","80-100"),
include.lowest=TRUE)
table(Vec.cut)
or determine the breaks automatically:
cut.size <- function(x, size) {
cut.prob <

cut.prob <- size/leng
In addition: the object MyNumberIs *is* created, but inside the
environment "attached" to the function as you evaluate it. And this
environment is gone when the function is done. (there is more to it, but
this is basically how it works). This is what Michael refers to in his
answer.
So, when

Dear list,
I have the habit of including rm(list=ls()) at the top of most of my
scripts. However, I wonder whether rm(list=ls()) gives the exact same
result as closing R and starting again fresh.
In other words, is it possible that there will be differences on how a

Thanks Uwe, that is really helpful.

Dear list,
I would like to get into the habbit of creating a package for each
project. That way I can package my project-specific functions and data
together and load or unload that at will. Also, it will allow easy
navigation through all the functions I will have available
for my info, why is this rarely a good idea? Is that the case for this
particular example , or is eval(paste()) generally rarely a good idea?

Perhaps this would be of help, you could use it as a starting point:

Dear list,
Suppose I have the following matrix:

[1,] "1" "3"

[3,] "3" "1"
[4,] "2" "3"

[6,] "5" "4"
[7,] "5" "4"
In this matrix, row 1 contains elements "1" an

to put all your dataframes into a
list and then run
lappy(cityList, dataCleaning) # for example
To get them into a list in the first place try this
n = 1997:2011
cityList<- vector(length(n), 'list')
for (i in n){
cityList[[i]]<- get(paste("city", i, sep=""

Dear list,
Excuse my ignorance, but I have gone through the R help (?parse, ?eval,
etc.) and still really don't know how to do the following.
I have the general following structure that I would like to automate
