names( d$columnname )
dear R wizards --- would it make sense for names(d$columnname) to be
"columnname"? I can preserve the columnname through x=subset(dataset,
select="columnname"), of course, but it would seem that x=d$columnname
could also do this. No? Sincerely, /iaw

Referencing a column using a function argument
Hi all,
I've been having trouble with something that seems like it should be
fairly straight forward. Any help at all from more experienced users is
appreciated!
I'd like to write a function that uses a column name as an argument.
However, I run into problems when I try to reference this column within
the function.
For example,
findCutoff <- function(tableName, columnName) {

using string variable as order() function argument
Hello,
In my script I would like to use a loop, which sorts the dataframe
according to different columns, pointed by the string variable.
id col1 col2 col3
1 10 0 4 8
2 11 1 2 2
3 12 0 8 3
4 13 0 5 5
Usually the order() function can be used like this:
sorted = mytable**[order(column3) , ]
which results in properly sorted table:

variable driven summary of one column
Hello,
how can I get a variable driven summary of one column of my data.frame?
Usually I would do
> summary(data$columnname) to get a summary of column named
"columnname" of my data.frame named "data".
In my case the columnname is not static but can be set dynamically.
So I save the chosen columname in something like
variable <- "columnname"
but how can I

question: how to select a column from a dataframe in a function
Hi,
I am creating a function and ran into the problem of selecting a column
from a dataset. It seems as though the $ function (as in data$columnname)
does not apply in the function. In simplified version:
This works:
testf2<-function(data,columnnumber){print(data[,columnnumber])}
But this doesn't:
testf<-function(data,column){print(data$column)}
Even though the first solution works,

What is this called? lapply(datum,"[[","ColumnName")
Hello R users
I recently learned how to use this command:
lapply(datum,"[[","ColumnName")
Unfortunately, I don't know how exactly it works, what it's called (in
particular the "[[" part], and what other things you can do with it
(retrieve multiple columns?).
Given datum is a list of dataframes with the same column, but different
number of rows,

detecting width overflow in serialized column with mysql
So I''ve got an ActiveRecord model pointing to a MySQL db, with an
auto-serialized column ("serialize :columnName").
Thing is, MySQL, depending on how it''s configured (like, by default),
has a bad habit of just truncating your data if it''s too wide for the
column, with no error raised. Yeah, I can probably reconfigure MySQL
and/or my AR connection to it. But

Unindent ERB output
Hi all,
I''d like to unindent a block of ERB specifically to combat the extra
spacing being added to content inside <textarea> by the browser. Is
there such a feature in ERB?
I shall denote indentation with underscores in the pseudo code example
below.
Thanks in advance,

assert_select trying to verify the presence of a textarea
Hello,
One of my functional tests looks like this:

post :edit, {:id => profile.id}

The test results in a failure, because the element cannot be found.

insert HTML <select> value into a textarea - Works in IE6, not in FireFox or Opera
I have a simple form at http://mstramba.com/fb5.html
It''s just a <select> and a textarea.
The idea is to be able to either type into a text area directly or
choose from a list of saved words in the select box. When a new choice
is made from the select, it automatically gets inserted into the text
area.
This code DOES work in I.E6 (on my machine (XP pro), but doesn''t

I''m trying to use the text_area() method and would like to populate the
text block with initial text.
According to this: http://dev.rubyonrails.org/ticket/3752 there was a
