Re: [R] Read a .sas7bdat file
Thank you for your answer. The big problems are : - I don't have SAS - I work on a linux system But, I've just found a solution : - I have downloaded SAS viewer (free) : http://www.sas.com/apps/demosdownloads/sassysview_PROD_8.2_sysdep.jsp?packageID=000176 - I have installed it with Wine. - Then, I can read my sas file and export it into a common format (csv...) This program works perfectly with Wine.

What is this program ? 2006/7/18, Greg Snow [EMAIL PROTECTED]: Others have suggested using R2HTML (which is a good option). Another option is to use Sweave and specifically the new odfWeave package for R. This works on OpenOffice files rather than word files (but OpenOffice http://www.openoffice.org/ can inport and export word documents). The basic idea is to write your report in OpenOffice (or LaTeX or HTML), but anywhere that you want statisticial output (graphs, tables) you include instead the R code to produce the table, graph, or whatever. Run this file through R (using Sweave or odfWeave) and the resulting file has replaced all the code segments with their output. The documentation with odfWeave has examples.

[R] reverse variables
Hello useRs,
Is there a way to reverse values of 2 variables (like with the language
Python) ? :
a - 1
b - 2
a, b - b, a
More specifically, I have a data frame :
famnum generation germain1 germain2 fa mo ptpn1 ptpn2 drb11 drb12
1 2 200 201 101 102 1 1 1 1
2 2 200 201 101 102 0 1 1 1
3 2 200 201 101 102 1 0 1 1
...
I don't want 0 in the seventh column, so I would like to have :
famnum generation germain1 germain2 fa mo ptpn1 ptpn2 drb11 drb12
1 2 200 201 101 102 1 1 1 1
2 2 201 200 101 102 1 0 1 1
3 2 200 201 101 102 1 0 1 1
...
I thought that a code like this would work :
if (ptpn1 == 0 ptpn2 == 1)
{
germain1, germain2 - germain2, germain1
ptpn1, ptpn2 - ptpn2, ptpn1
drb11, drb12 - drb12n, drb11
}
But R is not Python... Is there a way to do it easyly ?
Thank you.

?

[R] R newbie...
Hello,
I'm a new user...
I have a function :
calculate - function(x,y)
{
z - x + y
}
I would like to use the result (z) with another function :
recalculate - function(...)
{
a - z^2
}
But R says that z does not exist...
How can I use z in an another function ?
Thank you for your answer...

Re: [R] R newbie...
Thank you for your answer.
And what if my first function gives 2 results :
calculate - function(x,y)
{
a - x + y
b - x - y
}
How can I use both a and b in a new function ?

First of all, you might try reading the manual.
Second, you might try something like this:
calculate - function(x,y)
{
z - x + y z
}
recalculate(z)
{
a - z^2
a
}
z - calculate(x, y)
recalculate(z)
You need to return some value from your functions,
and you need to assign that value to a variable.
