Convert Decimal into Binary using Recursion in R
Converts a decimal integer to binary string recursively.
Program (R)
decToBin <- function(n) {
if (n == 0) return("0")
if (n == 1) return("1")
paste0(decToBin(n %/% 2), n %% 2)
}
print(decToBin(13)) Expected Output
[1] "1101" R Program to Concatenate Two Strings
Concatenates strings using paste0.
Program (R)
a <- "Hello"
b <- "World"
print(paste0(a, " ", b)) Expected Output
[1] "Hello World" Use Rscript from your terminal. Install R from
CRAN , save as
main.R, run
Rscript main.R. Or use RStudio.
No, base R only. All examples use built-in functions for maximum portability.
Yes, absolutely. Copy, tweak inputs, observe outputs — experimentation is the fastest way to learn.
Yes, fully cross-platform. R runs on Windows, macOS, and Linux. Works with R 3.6+.
