Sorting a vector by date
...tor of dates?
For example I have the vector
a<-ISOdate(2001, 1, 1) + 70*86400*runif(10)
How can this vector be sorted chronological?
And what's the function I should work with to handle these entries?
(in sense of: which(a>2001-01-04) or somehting like that)
Thank you for helping

turning list-elements into a vector
Hi.
Can anyone help me?
I want to create a vector from specific matrix-elements( e.g.[1,1]) these matrices are elements of a list.
Is there any possibility to work without a loop? (e.g. with "lapply"?)
hope, you can help me

(no subject)
Hi
I got a problem with creating a textfile:
how can I create a textfile, which has a headline like:
#data1
1 2 3 4
5 6 7 8
the problem is, how to bind text and matrix, so that the
"read.table"-function
will ignore the text and read the numbers.
Thank you for help

read ESRI file geodatabase feature classes
Hello-
Does anyone know if R can read in ESRI file geodatabase feature
classes, directly from the file geodatabase? I currently have to
export the data out of Arc, to a csv file, then read the csv file. I'd
like to bypass this step and read directly from the file geodatabase.
Thanks for your help.

export date field using sqlSave
Hello-
I'm receiving an error when I try to export a dataframe into Access
2010 containing a date field using sqlSave. The error I'm receiving
is:
[RODBC] Failed exec in Update
22018 39 [Microsoft][ODBC Microsoft Access Driver]Invalid character
value for cast specification
I can export all other columns, except the date column. If I convert
the date column to julian (numeric) it works
