Hi, I have a float that often looks like somthing like 2003.2 in my controller (1 decimal place) Is there a way to always show it to 2 decimal places eg 2003.20 ? Thanks Scott -- Posted via http://www.ruby-forum.com/.

Dear R-users: Hi, I read here ( http://stackoverflow.com/questions/2287616/controlling-digits-in-r) that R is only accurate up to the 15th decimal place, despite the fact that if you choose to display more decimal places, it will. I wonder if R uses the information beyond the 15th decimal place in actual computation. Thanks! Best, Xiao [[alternative HTML version deleted]]

Hi! I have a ftable object in which some row contains integers and some other contains a percentage that I would like to show with two digits after the dot. I tried something like ftblP[index,] = as.character(round(ftblP[index, ], 2)) where the index vector contains the number of the rows containing a percentage. My workaround works but it shows all numbers aligned to left, while I prefer that

I am a beginner in programmin in general and R specifically. I would like to generate a set of random numbers in a normal distribution but to limit the decimal places in these numbers to only 2. I have been using x1 <- runif(1,0,1) to generate my numbers. Can I add something to it to enable me to only get results rounded off to 6 decimal places? -- View this message in context:

... and see also ?print.data.frame , the "digits" argument. See also ?str It might be worth your while spending time with an R tutorial or two that covers such topics, i.e. distinguishing between an object and various (S3) methods that "represent" it, such as print(), summary(), plot() etc. -- Bert Bert Gunter "The trouble with having an open mind is that people keep

Dear R users, I need a function that gets a number and returns its number of actual decimal places. For example f(3.14) should return 2, f(3.142) should return 3, f(3.1400) should also return 2 and so on. Is such function already available in R? If not, could you give me a hint how to achieve that? Many thanks in advance. -----------------------------------------------------------------
