can't open file

I tried:

L <- readLines(con <- file("log2.log", encoding="UCS-2LE")
z <- read.zoo(textConnection(L), index = 1:2,FUN = function(x)
paste(x[,1], x[,2]))

Error:
Error en x[, 1] : n?mero incorreto de dimensiones

Please provide a reproducible example like this:

library(zoo)
L <- "4/4/200 10:10:10 3000
5/5/2000 12:12:12 4000"
read.zoo(textConnection(L), index = 1:2, FUN = function(x) paste(x[,1], x[,2]))

which gives me
 4/4/200 10:10:10 5/5/2000 12:12:12
             3000              4000
