It is quite unclear what you are importing from the CSV file. However it
seems your are unhappy with the dates that were first on the CSV.

Lets X be your imported data.frame from the CSV file and X[,1] be the
positions (dates)

If you want to have monthly positions without any gaps, I suggest you create
a timeSeries with data = X[,2:ncol(X)] and positions dreated with timeSeq().
If you want positions to be at the end of months, you just start on the
first of the next month and subsatrct 1. Ex: to obtain "01/31/2000"
"02/28/2000",... you just type :
timeSeq(from="2/1/2000",by="months",length.out=...)-1

Once you have a proper timeSeries, you can change the column names by using
colIds(X)<-c("name1","name2",...)
