Hi, I am having trouble converting numeric to characters in the format I desire. To be more specific, I have a number of numeric as follows: x<-c(1.0,2.0,2.00,2.1) I want to convert them to characters so that the out put would be c(?1.0?,?2.0?,?2.00?,?2.1?). However, I used as.character(x) and the output is: "1" "2" "2" ?2.1" The decimals are removed if the numeric ends with ?.0?. Is there a way to circumvent this problem? Thanks very much! Sincerely, Ruiyang Liu
Does this helps?> formatC(x, digits = 1, format = "f")[1] "1.0" "2.0" "2.0" "2.1" On Thu, Jun 7, 2018 at 10:08 PM ??? <ruiyangliu94 at gmail.com> wrote:> Hi, > I am having trouble converting numeric to characters in the format I > desire.

?formatC (digits, drop0trailing) ?sprintf (format %f) ?cat ?options (digits) You appear to be confusing source code formatting with output formatting. The internal representation of a numeric value has no notion of the number of decimals that were used to enter it into memory from source code. By the time you (or R) decide to re-convert it to a visual representation (characters), all trace of the original representation has been forgotten, so you have to be explicit about your output format, or R will make assumptions.

sprintf("%.1f", x)
sprintf("%.2f", x)
