[R-SIG-Finance] How to remove the error : Error in dimnames(x) <- dn : length of 'dimnames' [2] not equal to array extent

[pierre8r-list at yahoo.fr]

Hello,


The errors from the console :

> colnames(x) <- c('Open','High','Low','Close','Volume')
Error in dimnames(x) <- dn : 
  length of 'dimnames' [2] not equal to array extent



The complete script :

library(xts)
library(quantmod)
quotes <- read.csv2("K:\\00001-Compare\\Output\\OutputJBacktesting\\Quotes1HOUR.txt", header = FALSE, sep = ",", dec=".")
x <- xts(as.matrix(quotes[,-(1:2)]),as.POSIXct(paste(quotes[,1],quotes[,2]),format='%m/%d/%Y
%H:%M'))

colnames(x) <- c('Open','High','Low','Close','Volume')

barChart(x,TA=NULL)


Thanks,

Pierre8r
