r - Error on XLConnect::readWorksheet function -

-

i have line of r code giving me error. line of code is:

var <- readworksheet(paste(dir.censo, arq.variaveis, sep="/"), sheet = sheet.variaveis)

where dir.censo holds directory path of excel workbook , arq.variaveis name of variable holding file name. naturally sheet.variaveis holds name of worksheet need. file saved xlsx. here error:

error in (function (classes, fdef, mtable)  :    unable find inherited method function ‘readworksheet’ signature ‘"character", "character"’

i searched error online, nothing showed up. if me resolve problem, i'd appreciate it. system information in case need them:

operating system: windows 10

r version: 3.2.3

rstudio version: 0.99.473

java version: 8.0_66

again, lot.

i figured out how resolve issue. i'm posting answer here in case else runs problemj, search wouldn't fruitless. replaced line of code above following 2 lines:

wb <- loadworkbook(file.path(dir.censo, arq.variaveis)) variaveis <- readworksheet(wb, sheet = sheet.variaveis)

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
