The print() method for data frames has an option quote=, which you can set to FALSE:

print.data.frame(data.frame(x=c("Hello", "World")), 
                 quote=FALSE)
#       x
# 1 Hello
# 2 World

Edit:

With regards to the dputed data in the comment below:

as.data.frame(sapply(df, function(x) gsub("\"", "", x)))
