How to force R to print 2 decimal places in column of a data.frame? I tried to do so: x = inp(format(rounf(inp$Tamanho, 2), nsmall = 2),) where "INP" is data.frame and "Size" is the name of column. But has error: Error in eval.with.vis(expr, envir, enclos) : could not find function "inp" Lesandro Veja quais s?o os assuntos do momento no Yahoo! +Buscados

Hi everybody, I'm trying to set the number of decimals (i.e. the number of digits after the "."). I looked into options but I can only set the total number of digits, with options(digits=6). But since I have different variables with different order of magnitude, I would like that they're all displayed with the same number of decimals. I searched for it and found the format()

I am trying to use round()to force R to display a specific number of decimals, but it seems to display <=2 decimals no matter what I specify in the digits argument. As an alternative I tried signif(), but it also produces unexpected results. See example code and results below. Format() works, but then the result no longer is numeric. Am I missing something simple? I am using R 2.9.0 on Windows

Dear R users, I know of the possibility to import bitmaps via the nice pixmap library. But if you later on create a PDF it is somewhat disappointing to have such graphics bitmapped. Is there a trick (via maps?) to import a vector graphic and have them plotted onto a graph? My searching attempts in the searchable r-help archive did not seem to result in anything useful... Cheers, hinrich

Hello, I am using library fda and I can not run a lot of functions because I receive the error: Error in bsplineS(evalarg, breaks, norder, nderiv) : couldn't find function "spline.des" do you know how I can fix that? Thnaks. Liliana

Hi there, i'm not getting along with the following problem. I'd like to print a real number, e.g. x <- 12.3 with exactly two digits after the decimal point, e.g. 12.30 I've tried the whole format(), formatC() and prettyNum() functions but did not have any success with it. This should work with all real numbers, in case even with 0.0 (-> 0.00). For cracks this thing is pretty

Hello, For numbers in the range 100 to 100,000,000 I'd like to decimal align a right-justified comma-delineated column of numbers, but I haven't been able to work out the proper format statement. format(num, justify=right, width=15, big.mark=",") gets me close, but numbers larger than 1,000,000 project a digit beyond the right edge of the column, which I really don't

Good Day, I have the following: >Date<-c("08/05/08","08/06/08","08/07/08") >Weight<-c(209.4,211.8,210.0) >planned.meal<-cbind(Date,Weight) >planned.meal Date Weight 1 08/05/08, 209.4 2 08/06/08, 211.8 3 08/07/08, 210.0 >write.table(planned.meal, file="plannedMeal1.txt", + quote=FALSE, row.names=FALSE) output on

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

>From the help page of format, nsmall should control the number of digits. > format(0.123456789, nsmall = 10) [1] "0.1234567890" > format(0.123456789, nsmall = 1) [1] "0.1234568" > format(0.123456789, nsmall = 2) [1] "0.1234568" > format(0.123456789, nsmall = 8) [1] "0.12345679" It adds zeros fine but for

Hello All I am having a bit of trouble formatting my HTML with the desired number of digits after the decimal place. Am I doing something wrong/misunderstanding or is it a bug? Looking at the example supplied with ?HTML.data.frame: HTML(iris[1:2,1:2],nsmall=c(3,1),file="") Gives html output that includes the lines: </tr> <tr><td

Hello The data set I am examining has 7425 observations (rows with unique identifiers) and 46 samples(columns). I have been trying to generate a dataset that filters out observations that are "negligible" The definition of "negligible" is absolute value less or equal to 1.58. The rule that I would like to adopt to create a new data is: drop rows in which 2 or more

Hi, After reading the tutorial at http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1 I have the following question: What should I put instead of splashimage=(hd0,0)/grub/splash.xpm.gz and root (hd0,0) on /etc/grub.conf? Should I leave those lines untouched? If so, how would grub know where to boot from if /dev/sda fails? Or I would need to swap the drives in order to boot

Dear all; A simple? question. I'm having a problem with a math expression in the legend of a plot and I haven't found the way to get this to work, so any help will be appreciate. Basically I want to include in the plot is the R-squared and its numerical value, so I tried this: R2c<-0.82879 # R-squared of calibration model plot(1:10,1:10) legend("topleft",
