[R] readcsvIts() to create irregular time series

[Jan Verbesselt]

Dear,

Thanks for the previous tips about 'its' for importing the following
data.
5/10/1998,7
5/11/1998,5
5/12/1998,2
5/14/1998,1
5/15/1998,1
5/19/1998,1
5/20/1998,1

1. When using the following command;
test<-readcsvIts('Fires98.csv',informat=its.format("%m/%d/%Y"),header=FA
LSE)

the function reads in the data from the csv file as;
           V2
05/10/1998  7
05/11/1998  5

When testing if it's a its object
is.its(test) 
the result is FALSE.
When do you use informat or outformat? 
What goes wrong?

2. When reading in the data as a table;
m1 <- read.table('Fires98.csv',header=FALSE, sep=",", dec=".")
          V1 V2
1  5/10/1998  7
2  5/11/1998  5
...
test2 <- its(m1,dates=as.POSIXct(x=strptime(dimnames(V1)[[1]]
format=its.format("%m/%d/%Y"))) )...Doesn't work! 

I have difficulties defining the first V1 column as its object.

Thanks in advance for helping me out,
Jan
