Dear Friends.
Greetings!
I have asked the question of how to set up a blank file and write a list to
it as a row for many times, with the number of lists unknown.
I have received many beautiful solutions. Thanks go to Professor *Murdoch,
Professor *Menne, Professor Grothendieck and Dr. Olshansky. I have
organized the solutions below:
##########################################
*Set up a blank table in harddrive and write to it row by row*
*#Method 1*
*blank = data.frame(name=character(0), wife=character(0),
no.children=numeric(0))*
write.csv(blank, 'file1.csv', row.names=FALSE)
a1 = list(name="Tom", wife="Joy", no.children=9)
a2 = list(name="Paul", wife="Alic", no.children=5)
write.table(a1, file="file1.csv", sep=',', append=TRUE, row.names=FALSE,
col.names=FALSE)
write.table(a2, file="file1.csv", sep=',', append=TRUE, row.names=FALSE,
col.names=FALSE)**

*#Method 2*
*blank = data.frame(name=character(0), wife=character(0),
no.children=numeric(0))*
write.csv(blank, 'file2.csv')
a1 = list(name="Tom", wife="Joy", no.children=9)
a2 = list(name="Paul", wife="Alic", no.children=5)
write.table(a1, file="file2.csv", sep=',', append=TRUE, row.names=2,
col.names=FALSE)
write.table(a2, file="file2.csv", sep=',', append=TRUE, row.names=3,
col.names=FALSE)**

My problem now is, how to write a time series (instead of a list) to a csv
file? Also, how to set up such a csv file to accept the time series?
I know the length of the time series' but I do not know how many of them are
going to come up.
Examples are :
bb1=c(1:10)
bb2=c(101:110)
How to write bb1 and bb2 to a csv file and how to set up blank csv file to
accept such time series in the first place?
Your help will be highly appreciated!!!
Best Wishes!
