(newbie) Accessing the pieces of a 'by' object
Folks,
I know that I can do the following using a loop. That's been a lot
easier for me to write and understand. But I am trying to force myself
to use more vectorized / matrixed code so that eventually I will
become a better R programmer.
I have a dataframe that has some values by Year, Quarter and Ranking.
The variable of interest is the return (F3MRet), to be weighted
averaged within the

[plyr] Question regarding ddply: use of .(as.name(varname)) and varname in ddply function
Dear R-Helpers:
I am using trying to use *ddply* to extract min and max of a particular
column in a data.frame. I am using two different forms of the function:
## var_name_to_split is a string -- something like "var1" which is the name
of a column in data.frame
ddply( df, .(as.name(var_name_to_split)), function(x) c(min(x[ , 3] , max(x[
, 3]))) ## fails with an error - case 1

[solutions] "tapply versus by" in function with more than 1 arguments
Thanks to all.
I summarized (in order to thank the list) the solutions to help future workers searching subjects like this at R help.
# Number of rows
nr = 10
# Data set
dataf = as.data.frame(matrix(c(rnorm(nr),rnorm(nr)*2,runif(nr),sort(c(1,1,2,2,3,3,sample(1:3,nr-6,replace=TRUE)))),ncol=4))
names(dataf)[4] = "class"

Thank you Andrew, really appreciated.
I have now run 'samba-tool dbcheck --cross-ncs --fix' and it has
successfully fixed some errors; there were 110 previously, however there
are still 69 remaining after a second pass of dbcheck --fix.
The remaining errors seem to be mainly of this form:

"tapply versus by" in function with more than 1 arguments
Hi. I searched the list and didn't found nothing similar to this. I simplified my example like below:
#I need calculate correlation (for example) between 2 columns classified by a third one at a data.frame, like below:
#number of rows
nr = 10
#the third column is to enforce that I need correlation on two variables only

returning a modified fix()-ed dataframe
Dear all,
In order to ease the transition from SPSS to R for some of my colleagues, I am
trying to create a function which would show the variables and their labels
(if those exist), using function "label" in package Hmisc.
A toy example would be this:
my.data <- data.frame(age=c(24,35,28), gender=c("Male", "Female", "Male"))

Updating a Data Frame
Hi,
I have a global data-frame in my R script.
At some point in my script, I want to update certain columns of this
data-frame by calling in an update function.
The function looks like this:

set tkscale by tkentry
Hi, I am working under Windows and I am using R2.11
I want to use tkscale in my GUI. As the interval is quite big, I can't set
the scale to a certain specific value. Therefore I want to add tkentry to
allow the user to set tkscale to a certain value.
Here is the code
library(tcltk)

Thank you, Andrew - I hadn't done so. (In a good way, I haven't yet had
problems with samba that have caused me to delve quite so deeply into the
DB :) so I'm not as familiar with the range of tools as I could be, sorry!)
This has flagged up quite a few errors, all along the lines of:

Models with ordered and unordered factors
Hello;
I am having a problems with the interpretation of models using ordered or
unordered predictors.
I am running models in lmer but I will try to give a simplified example
data set using lm.
Both in the example and in my real data set I use a predictor variable
referring to 3 consecutive days of an experiment. It is a factor, and I
thought it would be more correct to consider it ordered.

Question about unicode characters in tcltk
hello list,
Can someone help me figure out why the following code doesn't work?
I'm trying to but both Greek letters and subscripts into a tcltk menu.
The code creates all the mu's, and the 1 and 2 subscripts, but it
won't create the 0. Is there a certain set of characters that R won't
recognize the unicode for? Or am I input the \u2080 incorrectly?
