Error while importing mice functions in R package -

i include mice::mice function in package perform imputation on data.

i use roxygen list imports

#' @param data dataset used imputation #' @importfrom dplyr select_ #' @importfrom mice mice complete #' @return list #' @export #'  impute_data <- function(data, vars, seed) {      data_used <- select_(data,vars)      mice_data <- complete(mice(data_used, seed = seed))      return(mice_data) } 

this function works fine when test code, when build package , try use it, following error

error in check.method(setup, data) :    following functions not found: mice.impute.pmm,mice.impute.pmm, mice.impute.pmm, mice.impute.pmm, mice.impute.pmm  

i tried add imports functions mentioned in error had no effect whatsoever on outcome.

what missing? i've never found such problem.

you forgetting handle description file! handle impute_data.r.

your question quite similar to: what roxygen should put when use function of package in function

i gave answer there (please search similar questions before posting question). case:

first, being aware of your

sessioninfo()  getwd() # r's working directory .libpaths() # r's library location 

step0 download , install necessary packages:

library(roxygen2) library(devtools) library(digest) 

step1 put related ".r" files (yourfunction1.r, yourfunction2.r, yourfunction3.r, impute_data.r) r's working directory.

step2 create package skeleton in r's working directory: sure there no folder named "yourpackage" in r's working directory before running following command. (from r's console)

package.skeleton(name = "yourpackage", code_files = c("yourfunction1.r", "yourfunction2.r", "yourfunction3.r", "impute_data.r"), path = ".") 

after running package.skeleton, folder yourpackage created in r's working directory.

delete read-and-delete-me file windows explorer.
delete "yourpackage-package.rd" file in yourr'sworkingdirectory\yourpackage\man folder
(do not delete "yourpackage.rd" file in yourr'sworkingdirectory\yourpackage\man folder!)

step3 @ end of preamble of ".r" file (impute_data.r), put following (if had not done in step1):

#' @importfrom mice mice #' @importfrom mice complete #' @export impute_data <- function(...) {... 

step4 in description file of package, in imports part, add:

imports:     mice(>= versionnumber) 

where versionnumber version number of mice package using. can find version number right-click function (from yourpackage) in object browser of revolutionrenterprise; , going bottom of resultant .html file. there, version number of package shown.

in step2, package.skeleton automatically produced namespace file content is:

exportpattern("^[[:alpha:]]+") 

do not handle namespace file manually.

step5 roxygenize package wanna create ("yourpackage")

library(roxygen2) roxygenize("yourpackage") 

upon roxygenization, content of namespace file of yourpackage automatically converted exportpattern("^[[:alpha:]]+")

# generated roxygen2: not edit hand  export(impute_data) importfrom(mice,mice) importfrom(mice,complete) 

step6 build package:
(first, delete "src-i386" , "src-x64" folders (if any) in yourr'sworkingdirectoryfolder\yourpackage folder windows explorer)
(be sure again there no "yourpackage-package.rd" file in yourr'sworkingdirectory\yourpackage\man folder. if there is, delete before building)

build("yourpackage") 

step7 install package:

install("yourpackage") 

step8 check going loading package , running function in package.

library(yourpackage) impute_data(a,b,1235) # "impute_data" function in package "yourpackage" 

step9 check package loadable cran (comprehensive r archieve network) (if wanna share package):

(first, delete "src-i386" , "src-x64" folders (if any) in yourr'sworkingdirectoryfolder\yourpackage folder windows explorer)
(be sure again there no "yourpackage-package.rd" file in yourr'sworkingdirectory\yourpackage\man folder. if there is, delete before checking)

from dos command prompt:
start – cmd - enter. pass r's working directory (your r's working directory known via getwd()) , cran check:

cd c:\users\user\documents\revolution r cmd check yourpackage 

from r's console:

devtools::check("c:/users/user/documents/revolution/yourpackage")
