How to generate random samples rounded to 4 decimal places in R?
Random samples can be generated in many ways such as using discrete and continuous distributions, using integer vectors, using numerical vectors, using character vectors and/or factor vectors, also with columns of a data set. If we have the sample that is continuous in nature then the values are likely to contain many values after decimal point and we can limit those values to 4 or use any other limit using round function.
Example
x1<-round(rnorm(10),4) x1
Output
[1] 0.1667 -0.5536 -0.2748 -0.1064 -0.7740 0.0009 0.3966 -0.2256 -0.4090 [10] 0.4069
Example
x2<-round(rnorm(50,545,18.5),4) x2
Output
