Hello, I am relatively new to using R. The text file contains the date and price . I want to read and manipulate the data in R. However, when I use read.table, it treats all of the data as "factors" and I do not know how to treat the data as numbers:
http://r.789695.n4.nabble.com/file/n4498828/p_diarios.txt p_diarios.txt setwd ("C:\\Users\\Sandro\\Dropbox\\R") data.precios <- read.table ("p_diarios.txt ", header =TRUE , dec=",", sep="\t") Time <- data.precios$time # 01.02.2004 - 12.05.2011 Price <- data.precios$price # Historical spot price log.Price <- log(data.precios$price) Error en Math.factor(c(12L, 126L, 213L, 342L, 160L, 186L, 219L, 37L, 54L, : log not meaningful for factors As you can see, I cannot calculate the price logarithms. Any help is appreciated.
