Full_Name: Dirk Jacob Version: R 2.8.1 and 2.9.1 OS: Win XP Submission from: (NULL) (153.96.32.62) I want to convert numbers to strings like: > inputs= c(0.3+0*(1:12) ) > (format(inputs,digits=3,scientific=T,collapse=" ")) and it works [1] "3e-01" "3e-01" "3e-01" "3e-01" "3e-01" "3e-01" "3e-01" "3e-01" "3e-01" [10] "3e-01" "3e-01" "3e-01" if I use different numbers i...

...beating my head against this problem for a bit, but I can't figure it out. I have a series of strings of variable length, and each will have one or more numbers, of varying format. E.g., I might have: tmpstr = "The first number is: 32. Another one is: 32.1. Here's a number in scientific format, 0.3523e10, and another, 0.3523e-10, and a negative, -313.1" How could I get R to just give me a list of numerics containing the numbers therein? Thanks very much to the regexp wizards! Cheers, Nick -- ==================================================== Nicholas J. Matzke Ph...

Dear Helpers, I would like to export a large dataset to a txt file in order to use it in an other programm. Unfurtunatly the R the scientific format is a small e: 2 e-1 while the other programm requires the format to be a capital E: 2E-1 How can I change this in R? Thanks for your help PS: I already found the command to turn them into a non scientific format (scientific=FALSE) [[alternative HTML version deleted]]

R developers, Seems I get a bad result ("%#4.0-1e" in particular) when trying to use prettyNum digits=0 with scientific notation. I tried on both my Linux box and on an online R evaluator and saw the same problem, so it's not limited to my box at least. I see the problem in both R 3.5.3 and R 3.3.2. options(scipen=-100) prettyNum(1, digits=0) [1] "%#4.0-1e" prettyNum(2, digits=0) [1] "%#4.0-1e&...

Dear List: Below is how I specify an axis: axis(2, at=c(0.00005, 0.0005)) R displays the numbers in scientific notation. What argument/parameter should I use to tell R to display the numbers as specified rather than in scientific notation? > version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor...

Hey folks, I was just reminded of the Scientific distro, which on the surface appears to be quite similar to CentOS even when the developers over there are rather coy about which Enterprise Linux distro they base theirs on. I wonder if anyone here has done a comparison of the two that they'd care to share. I work in a Scientific Research...

PROBLEM `signif' does change to scientic notation at different levels depending on the number of significant digits in the input. This can generate tables where figures change ``irregularly'' from normal to scientific notation. PROPOSAL The change to the scientific notation should be made only if the figure in scientific notation - with potentially as many significant digits as given as argument to the call of `signif' - would be shorter than the figure in normal notation. EXAMPLE te...

We''re developing a system that''s used for tracking company IPO data and we''re running into a few number storage issues. For large numbers, i.e. numbers greater than 100 million, MySQL insists on storing these as scientific notation. I don''t really have a problem with that but when we want to edit these fields using something like: <% form_for(@company) do |f| %> <p> <%= f.text_field :some_large_number_field , :size => 20 %> <%= f.submit "Update" %> </p&...

While I'm very pleased with the results I get with rpart and rpart.plot, I would like to change the scientific notation of the dependent variable in the plots into integers. Right now all my 5 or more digit numbers are displayed using scientific notation. I managed to find this: http://tolstoy.newcastle.edu.au/R/e8/help/09/12/8423.html but I do not fully understand what to change, and to what.

Greetings! I have just signed up to r-sig-fedora because I have installed Scientific Linux 6.2 (my first Red Hat based Linux since over 10 years ago ... ). I'm trying this for basically 2 reasons: first, I expect CERN and FermiLab should do a good job of maintaining their distribution, and in particular to take care of its compatibility with scientific software; second, becau...

Hello R users, I am a bit puzzled by the fact that options(digits=22) x0 <- 69880 y0 <- 26185 x1 <- 69600 y1 <- 22937 number <- paste(x0,y0,x1,y1,sep="") number <- as.numeric(travel) print(number) gives number in scientific notation (some precision is wasted by having a "e+19" at the tail): 6.988026185696e+19 but print(exp(log(number))) gives the full 20 digits of number (albeit with a certain error due to the log() and exp() transformation): 69880261856959807488 How can I set print(number) to the n...
