You left out all the most important bits of information. What is yo? Are you trying to assign a data frame to a single column in another data frame? Printing head(samples) tells us nothing about what data types you have, especially if the things that look like text are really factors that were created when you used one of the read.*() functions. Use str(samples) to see what you are dealing with.
