parse_svec
and deparse_svec
parse_svec
converts characters like "7-10,14-15"
to numeric vectors
parse_svec("7-10,14-15")
deparse_svec
reverse the process
deparse_svec(c(2,5,3,1,7))
Parameter max_lag
in deparse_svec
changes the threshold of integers collapsed together:
deparse_svec(c(1,2,4,7,11)) deparse_svec(c(1,2,4,7,11), max_lag = 2) deparse_svec(c(1,2,4,7,11), max_lag = 3)
The goal is to work as an alternative to retrieve system information. For example, R doesn't provide functions to get memory limits, or CPU chip-set information on Linux or MacOS.
# Total RAM in bytes get_ram() # Print-friendly to_ram_size(get_ram(), 1024) # WARNING: $free is the total RAM - R usage, is no the actual free RAM mem_limit2()
askYesNo
comes with utils
package allows to ask yes/no questions and returns logical value. If cancel
is entered, then the function returns NA
, if answers other than yes
, no
or cancel
is given, it raise an error. dipsaus::ask_yesno
will ask the question again and again until the user actually say yes
or no
> ask_yesno('Please answer an yes/no question, ok?') ## ♥ Please answer an yes/no question, ok? (Yes/no): > qweee ## ⚠ Please answer Y/yes, N/no, or c to cancel. (Yes/no): > ttt ## ⚠ Please answer Y/yes, N/no, or c to cancel. (Yes/no): > y ## [1] TRUE
ask_or_default
instead of asking a yes/no question, it asks a question with default answer. User don't have to type the answers if the they accept defaults:
> ask_or_default("What is your password", default = 'I will not tell you!') ## ♥ What is your password ## [default is ‘I will not tell you!’] > ## [1] "I will not tell you!"
