Write.table query

Hello,

I have the following 'write.table' statement which works fine

write.table(DataOutput,"c:/Prices.csv",append = TRUE,col.names = NA,sep
= "," )

My query is, how could I modify this so I can include a variable name as
a prefix before the 'Prices.CSV' filename.

For example:

prefixname = "DevX"

write.table(DataOutput,"c:/" &prefixname& "Prices.csv",append =
TRUE,col.names = NA,sep = "," )

With the resultant CSV output to be named "DevXPrices.csv".

Use `paste':

prefixname <- "DevX"
paste("c:/", prefixname, "Prices.csv", sep = "")

[1] "c:/DevXPrices.csv"

Hello,

I have used "prcomp" and the variances for the first 3 PC's are 2.65, 
1.97 and 0.38.

When I plot the principal component values for each data point I can see 
that the points lie in a plane as one might expect from the variances.

But this plane is diagonal through the 3D space of the first 3 PC's.  My 
question is: is it usual to follow a PC analysis with an eigen analysis 
to align this plane with with 2 principal directions, or is there a way  
of incorporating this into "prcomp".

Thanks, David
