Hi,
I understand this should be an easy task but I am still struggling a bit to
read a .txt file with a date vector. My code is as below:
data<-read.table(file.choose(),header=TRUE,sep="\t",dec=",",colClasses=c("Date","numeric","numeric","numeric"))
But I am getting an error:
Error in charToDate(x) :
character string is not in a standard unambiguous format
because my date vector is in a format below:
format="%d.%m.%Y"
But how can i define the date format for date vector in read.table
function....?
It is easiest to simply read the column as character, and convert
later by as.Date(x, format="%d.%m.%Y")
You might want to consider using read.delim2 to get all the usual
defaults for a tab-delimited file in a locale using comma as decimal
separator.
Br,
Jack
