Hello,
Try something like that:
> lgd <- format(Sys.time(), "%Y_%m_%d_%H_%M_%S")

Dear R helpers,
I am using Beta distribution to generate the random no.s (recovery rates in my
example). However, each time I need to save these random no.s in a csv format.
To distinguish different csv files, one way I thought was use of Sys.time in
the file name. My code is as follows -
# My code
rr = rbeta(25, 6.14, 8.12)
lgd = 1 - mean(rr)
write.csv(data.frame(recovery_rates = rr), file = paste("recovery_rates_at_", Sys.time(),
".csv", sep = ""), row.names = FALSE)
However, I get following error -
Error in file(file, ifelse(append, "a", "w")) : cannot open the connection
In addition: Warning message: In file(file, ifelse(append, "a", "w")) :
cannot open file 'recovery_rates_at_2012-07-04 1:14:05.csv': Invalid argument
If instead of Sys.time, I use some other variable e.g. lgd as
write.csv(data.frame(recovery_rates = rr), paste('rates_',lgd,'.csv', sep =
""), row.names = FALSE)
I am able to store these simulated recovery rates in different files. But I
need to use Sys.time in my csv file name. (or is there any other way of writing
these csv files so that files don't get over-written).
Kindly guide.
Regards and thanking in advance
Vincy
