[R] Number of digits to display?

How do I control the number of digits to display, say, in a matrix, without rounding or losing accuracy in subsequent calculations? round() of course reduces accuracy. Also, if all my results are really fractions, is there a way to display them as fractions of integers rather than

Re: [R] Formating time in R

Raoni, You could write your own function to do this. For example, using the period class from the R package lubridate, you could do something like this: days2 <- function(x) { h1 <- 24*x h <- floor(h1) m1 <- 60*(h1 - h) m <- floor(m1) s <- round(60*(m1 - m)) new_period(second=s,

Hi Alexander, I suspect that when you write "try" you mean that you try to run the function with some value for "pid". The "unexpected symbol" error message usually includes the offending symbol and that will probably identify the problem. Jim On Mon, Oct 26, 2015 at 1:20 PM,

You can also use the na.exclude function, which is like na.omit but attaches an attribute, "na.action", telling which rows were removed. Then use the naresid function to insert NA's into the right places in the output of the function that only works properly on NA-less data. E.g., cleanData <-
