title: Is there a simple way to convert a list to a column dataframe in R?
body: <p>I have a list of POSIXct (timestamps) data that I want to put in a single-column data frame. Using the as.data.frame function gives me instead each timestamp in a single columns, so that the dataframe is 1 x n instead of n x 1. I cannot convert back to a matrix first or use the t() function as this will force the values back into a numeric form. Is there a way to directly go from the list to the dataframe?</p>
  <p>Thanks!</p>
