I bet apply has a solution
Hi all 
For the data below, I would like to return a logical value indicating
differences in the data.
#Create data
Data..<-data.frame(a=rep(1,10),b=c(rep(1,9),2),c=c(rep(1,8),2,2))
   a b c

6  1 1 1
7  1 1 1
8  1 1 1
9  1 1 2
10 1 2 2
So what I want is to return logical value telling me if all the values are
the same.  So the result would be a b

Sorting a data frame by specifying a vector
Hello all, 
   I cannot seem to figure out this seemingly simple procedure.  
I want to sort a data frame by a specified character vector.
So for :
df.. <- data.frame(Season=rep(c("Summer","Fall","Winter","Spring"),4),Obs=
runif(length(rep(c("Summer","Fall","Winter","Spring"),4))))
I want to sort the data frame

List elements of NULL to value
Hi everyone, 
    I am posting this because i know its easy and i cant for the life of me
figure out how to do it though i have tried and through a ridiculously
complex loop made it happen.  I need to convert some list elements of NULL
value to 0s so they mesh with my data frame properly.  So for 
A<-list(1,NULL)
returns
[[1]]
[1] 1
[[2]]
NULL
Would instead return
[[1]]
[1] 1
[[2]]
[1] 0

To Try or to TryCatch, I have tried to long
So after about 4 hours struggling with Try and TryCatch I am throwing in the
towel.  I have a more complicated function that used logspline through
iterative distributions and at some point the logspline doesnt function
correctly for some subsets but is fine with others so I need to be able to
identify when the error occurs and stop curtailing the distribution and I
think this Try or TryCatch

Summarizing elements of a list
Hi everyone, 
   I looked around the list for a while but couldn't find a solution to my
problem.  I am storing some results to a simulation in a list and for each
element i have two separate vectors(is that what they are called, correct my
vocab if necessary). See below
Version1_<-list()
for(i in 1:5){
	Version1_[[i]]<-list(First=rnorm(1),Second=rnorm(1))

Alter character attribute
Hi everyone
I have some records that include a date attribute for the date and time but
i need to separate the data and analyze it separately in GIS by Month and
Year, so i need to pull these attributes out and create their own attribute
field.  
So the input:
RawData2.. returns
  ID   period_end_date
1 22 9/10/2007 0:00:00
2 44  2/2/2006 0:00:00
and i need to get

Subsetting for unwanted values
Hi all, 
   I have toyed with this for too long today and in the past i used multiple
lines of code to get at what i want.  Consider the following:
All i need to do is subset Pc to the values that do not equal Pc.X.  The
first attempt doesnt work because i have unequal lengths.  The second
attempt doesnt give me an the right answer.

Dont show zero values in line graph

   Im getting better at plotting my data but cant for the life of me figure
out how to show a line graph with missing data that doesnt continue the line
down to zero then back up to the remaining values.

Pie Chart in map
Hey R'rs, 
    So im sick of dealing with ESRI products and am looking to stream line a

have not yet seen a map that puts pie charts within the map to help
represent data like the attachment.

Summarize by two or more attributes
Okay everyone heres a likely softball for someone.
Consider the following data frame:

x<-rep(c(1,15),10)
y<-rnorm(20)
z<-c(rep("auto",10),rep("bus",10))
a<-rep(c(1,1,2,2,3,3,4,4,5,5),2)
#Create Data frame

I want to create a new column the equals the sum of the Rates for each type

Using object as literal value in list vector
Hello all , 
  This is a pretty simple question I think but cannot find an answer on the
list or in my brain.  I would like to iterate through a loop and use a
vector of strings to name a number of list elements.  For instance 
       #Create vector of strings
	Et<- c("ACC","RTL","WHL")
	MeanValues_ <- list("ACC" = 1000, "RTL" = 2000,

footnote:id, colons and jquery
I just received a [bug report] for Python-Markdown complaining that
colons are used in the ids of footnotes. For reference, we [output]
the same format at PHP Markdown Extra. The general complaint is that
the colon in the id attribute (`id="fnref:1"`) causes jquery to choke
when referencing that id from javascript because jquery uses colons to
indicate pseudo elements (as does CSS). As

Convert COLON separated format
I have a bunch of data sets that were created for the libsvm tool.  They are in "colon separated sparse format".
i.e.
1  5:1  27:3  345:10
Is a row with the label of "1" and only has values in columns 5, 27, and 345.
I want to read these into a data.frame in R.  
Is there a simple way to do this?

Cut including the 0 value as separate bin
Hi everyone,   
I have been using R too long to have to ask this but here i am.  How do i
create a separate bin for the 0 value?  So for:
#Create data frame
DF<-data.frame(A=0:20)
#Create label vector
labs<-1:6
#Create buckets and label
DF$Cut<-cut(DF$A,c(0,4,8,12,14,16,20),labels=labs,include.lowest=TRUE)
I want the 0(zero) value to be in a separate bin.  
Sorry for the lame post...
