This mailing list truly is amazing.
Thank you so much for all the help!
I feel a little strange asking something that "simple" again, but I wasn't able to find it in the help...
Is there a way to tell R how to display numbers (double)? How many numbers after the decimal point, etc...
Yes. print() has a digits= option, and there are global options that affec the number of digits
Eg:
micropi<-pi*1e-6
nanopi<-pi*1e-9
megapi<-pi*1e6
gigapi<-pi*1e9
options("digits")
$digits [1] 7
options("scipen")
$scipen [1] 0
pi[1] 3.141593
micropi[1] 3.141593e-06
nanopi[1] 3.141593e-09
megapi[1] 3141593
gigapi[1] 3141592654
[1] 3.142
options(digits=4) pi
micropi[1] 3.142e-06
nanopi[1] 3.142e-09
megapi[1] 3141593
gigapi[1] 3.142e+09
[1] 3.142options(scipen=4) pi
micropi[1] 0.000003142
nanopi[1] 3.142e-09
megapi[1] 3141593
gigapi
