Re: [R] Latex: Date Format conversion

 Marc:
My report is done every two weeks and is created automatically. I click a command button on an Excel form and it runs a .rnw script in R creating a latex dynamic report. Excel sends 15 days of data to R, eg: 6/1/10 to 6/15/10. Right above my report I usually write the range of the report manually, something like "Report from 6/1/10 - 6/15/10" so I want to see if latex can select that range of dates dynamically because my report dates are constantly changing. I would like latex to look at the beginning and last date of my report and fill out the dates on the fly. I can do this easily with the following:
Report from \Sexpr{report[1,1]} & - & \Sexpr{report[1,15]} and it prints the correct values:
Report from 6/1/10 - 6/15/10
But I want those values formatted like this: Report from June 01, 2010 - June 15, 2010 I am looking for a latex command to convert the dates, something like this pseudo-code: Report from \longdate\Sexpr{report[1,1]} & - & \longdate\Sexpr{report[1,15]} Where long date will be the format that converts 6/1/10 to June 01, 2010
Thanks for helping.

Felipe,

Do you want the report to be dated for the day

If so, just use:

 
> \today

to generate the current date at run time in the long format that
