Pretty printing numbers
Friends
I am trying to format a number to a string so 2189.745 goes to "2,189.35"
and 309283.929 goes to "309,283.93"
I have tried to use formatC(X, big.mark=",",drop0trailing=FALSE, format="f")
but it does not get the number of decimals correct. Specifying digits does
not work as that is significant digits. I could use a switch statement
switching on

base::format adds extraneous whitespace for some inputs
Dear R Core Team,
First of all, thank you for your amazing work on developing and
maintaining this wonderful language.
I just stumbled upon the following behavior in R version 3.6.0:
format(9.91, digits = 2, nsmall = 2)
format(9.99, digits = 2, nsmall = 2)
yield "9.91" and " 9.99" with an extraneous whitespace.
My expected output for the second command is

Bug/Error in formatC? (Was: Why doesn't formatC( x, digits=2, format= "g")...)
Hi all
After posting what follows, Duncan Murdoch suggested perhaps a bug
in formatC, or an error on documentation. Any comments?
In particular, bug, error or not, any ideas about how I can
consistently get two significant figures to print?

Bug or new concept in formatC?
As a sequel to my previous mail on cut, formatC does not produce
what I have been taught is significant digits:
> x <- c(1.0793,1.0796, 11.0954, 11.0736 )
> formatC(x,digits=3,format="g")
[1] "1.08" "1.08" "11.1" "11.1"
(3,3,3,3) significant digits OK
> formatC(x,digits=3,format="f")
[1] "1.079"

Why doesn't formatC( x, digits=2, format="g") doesn't always give 2 sig figs?
Hi all
I am not a C programmer, but I am trying to understand formatC to
get consistent printing of reals to a given number of significant
digits.
Can someone please explain this to me? These first three give what

I'm sure I'm missing something with formatC() or sprintf()
I have a four-digit string I want to convert to five digits. Take the
following frame:
zip
2108
60321

22030
91910
I need row 1 to read '02108'. This forum directed me to formatC previously
(thanks!) That usually works but, for some reason, it's not in this
instance. Neither of the syntaxes below change '2108' to '02108.' The values

Commas in formatC
formatC() is great for formatting numbers! But it would be even better if it
could optionally insert commas (or semicolons), e.g.
R> formatC(1234567.89, digits=2, format="f", commas=T)
[1] "1,234,567.89"
Here's a snippet of code that does that, which could more or less just be
inserted into at the end of formatC if any R-core guru were so inclined. "r"

Export data frame of high dimension to txt
I managed with success to export a data frame of 367 columns and 37 rows to a txt file, but unfortunately I couldn't manage the same with the transposed data frame. Specifically, it seems like the notebook cannot "read" correctly 367 columns, so it reads the first 145 columns and it folds down the rest of them and consequently it folds down the respective data.

formatC slow? (or how can I make this function faster?
I'm trying to convert a matrix of capture occasions to format that an
external program can read. The job is to basically take a row of
matrix, like
> smp[1,]
[1] 1 1 0 1 1 1 0 0 0 0
and convert it to the equivalent string "1101110000"
I'm having problems doing this in a speedy way. The simplest solution

expression exponent labeling

I want to label an axis with exponents, but can't get it done with expression.
Any hints would be very welcome!

small bug in formatC?

The problem, if it is one, is in .format.zeros:
.format.zeros("0.000", "xxxxxx")

base::format adds extraneous whitespace for some inputs
I can reproduce this.
It has to do with whether the value rounds down to 9 or up to 10, and
thus needs another space, I think. I agree that it shouldn't happen,
but at least you can get rid of the space by using trim = TRUE.
# rounds to 9 vs 10
format(9.95, digits = 2)
format(9.96, digits = 2)
format(9.95, digits = 2, nsmall = 2)

Similarly for flag=[SnZ].

Formatting in formatC and format (PR#129)
[This turned into a bug report which will go to r-devel, so I have taken it
off r-help.]
Bugs reported here:
(1) formatC's help page need some clarification.
(2) formatC needs to treat modes "double" and "real" as equivalent.
(3) format's help page or (preferably) format needs correction re the
meaning of `digits'

documented/undocumented behavior of as.double(formatC(x, digits=17))
Some days ago, there was a discussion about the command
formatC(exp(1),digits=100,width=-1)
Converting a double value to a string, from which the double may be
reconstructed exactly, may be useful. So, I did some experimentation
with it in my linux installation of R-2.5.0.
I generated a vector x of a large number of random doubles (random sign,
random mantissa with 53 significant bits and

inconsistencies between formatC(), format() and format.char()
Dear R-Developers,
Just a note: there are some inconsistencies between formatC(), format() and
format.char() and cross calling between these functions.
On the one hand

{\"}
> cat(format.char('{"}'), "\n")
{\"}
is by default format.char(, flag="-") and thus by default calling format()

formatC with format="fg" displays number in exponential notation (PR#2299)
