Recipe 2.1

The Text String to be printed is

The punctuation characters in the ASCII table are:

    !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~*

capture " by using ' as quotes

cat(s1 <- 'The punctuation characters in the ASCII table are: !"#$%&') print(s1)

caputre ' by using " as quotes

cat(s2 <- "'()*+,-./:;<=>?@[") print(s2)

\ will capture the first whack \ #(are we using whack for \ ? :)

cat(s3 <- "]^_`{|}~") # the \ works print(s3)

(subject <- paste0(s1,s2,s3)) #it stores the first wack but with "" stating and ending

cat(subject) #this Cat option solved that problem of extra " " in begining and end

Recipe 2.2

Match a string of the following ASCII control characters: bell, escape,

form feed, line feed, carriage return, horizontal tab, vertical tab.

These characters have the hexadecimal ASCII codes 07, 1B, 0C, 0A, 0D, 09, 0B.

Getting ASCII codes upto 150

coderange = c(1:150) asciitable_toprint = data.frame( coderange, as.raw(coderange), row.names=rawToChar(as.raw(coderange),multiple=TRUE) )

colnames(asciitable_toprint) <- c("dec","hex") asciitable_toprint

Putting dec no. only of given seven hexadecimal ASCII codes 07,1B,0C,0A,0D,09,0B

coderange= c(7,27,12,10,13,9,11) asciitable_printable_seven = data.frame( coderange, as.raw(coderange), row.names=rawToChar(as.raw(coderange),multiple=TRUE) ) colnames(asciitable_printable_seven) <- c("dec","hex") print(asciitable_printable_seven)

@wibeasley I have tried recipe 2.1 and 2.2. There are duplicate issues posted for these two problems. Can you remove one of them please?

wibeasley commented 8 years ago

I can, but I'd prefer you learn. Here's my suggestion:

Close the issue (with an explanation that you created a duplicate).
Edit the title of the issue by appending something like "-duplicate of Issue #1" (or whatever you duplicated.
