Hey people..
Wrong 'people': this is a question for R-help, and please study the
R posting guide.
I have been trying this code
write.table(data.frame(date,name,amount,details),file="C:/Documents and
Settings/Administrator/My Documents/Account/Account
Info.txt",quote=FALSE,append=TRUE,col.names=FALSE,row.names=FALSE,sep="\t")
check<-read.table("C:/Documents and Settings/Administrator/My
Documents/Account/Account
Info.txt",col.names=c("Date","Name","Amount","Details"),header=FALSE,sep="\t",
na.strings="NA")
#My na.strings="NA" is not showing NA's in blank entries
It is not documented to.
# check$Date is of the format("%Y-%m-%d")
Really? I think most likely it is a character string.
# I want to change it to
check$Date<-format(check$Date,"%d-%m-%Y")
# I get this error
Error in switch(mode(x), "NULL" = "NULL", character = .Internal(format(x, :
invalid 'trim' argument
Did you read ?format: trim is the second argument, and this is not a
valid value.
HELP
So, please read the posting guide and post a complete reproducible example
there. Then people may be prepared to help you, if they believe you have
made a reasonable effort to help yourself.
