Sjlabelled::get_label() %>% # pull labels from original tibbleД®nframe() %>% # convert list of column names to a new tibble Set_names(titanic %>% # convert variable names to informative labels Mutate_all(as_factor) %>% # convert all variables from chr+lbl to fct type WeвЂ™ll also convert the variable names to their more descriptive labels if applicable, using sjlabelled::get_label, and clean up the names to be all lowercase and replacing the spaces with underscores using janitor::clean_names(). We can use as_factor() to convert these variables to fct variables keeping and showing only the labels. Notice that each variable is a dbl+lbl type. As an example, we will use the titanic.sav dataset, which can be downloaded from Butler UniversityвЂ™s PS 310 course datasets here. Note that at the time of this writing, the write_sas() function is still experimental and only works for limited datasets. To write the file back out to SAS, use write_sas(). Now the tibble in R contains the descriptive variable names and values from the labels stored in the original SAS data files. # вЂ¦ with 1 more variable: `What grade are you in?` Д®ven better. # `Month of adminвЂ¦ `Day of adminisвЂ¦ `How old are yoвЂ¦ `What is your sвЂ¦ Set_names(nyts %>% sjlabelled::get_label() %>% enframe() %>% pull(value)) # 5 Q3 What grade are you in? # convert column names to variable label using purrr::set_names() Sjlabelled::get_label() %>% # pull column names from tibbleД®nframe() # convert list of column names to a new tibble # A tibble: 5 x 2 Now we have the value labels showing up, but what do Q1, Q2, and Q3 mean? These have a label attribute that we can extract and show in our tibble using the get_label function from the sjlabelled package. Mutate_at(vars(Month, Q1:Q3), as_factor) # convert Month, Q1, Q2 and Q3 from chr+lbl to fct column type Mutate_all(zap_empty) %>% # convert any blank cells to NA We would prefer these to be showing as NA in R, instead of an empty character. Factor ( fct) variables are what R calls categorical variables.ДЄnother thing to clean up are the blank cells. If you want to convert the chr+lbl variables to a traditional categorical variable that is internally stored and represented in the output as the labels, use the as_factor() function.

These chr+lbl columns imported by haven are labeled categorical variables in SAS and treated as categorical variables in R, but show up as numeric values (e.g.В 1, 2, 3) in the R output. sas7bcat file that is stored behind the scenes. sas7bdat file is what is shown in the tibble by default, but the data also contain a label from the. Notice that each column is a chr+lbl type, meaning the character value from the. Select(Month:Q3) # keep only first few cols for example Both will be specified as arguments in read_sas(). sas7bdat file and the formats/labels in a. The data comes in two files, the raw data in a.

We will use the National Youth Tobacco Survey (NYTS) data from 2017, which can be downloaded from the CDC website here. dta files into R is the readstata13 package, which, despite what the name suggests, can read Stata 13 and Stata 14 files.LetвЂ™s start with an example of reading in a SAS dataset.

The read.dta function in the foreign library was popular in the past, but that function is now frozen and will not support anything after Stata 12.

The read_dta function in haven is a wrapper around the ReadStat C library.

dta files in R, please feel free to post them below. If you have questions-and suggestions-about working with. This gets parsed correctly in the csv files but not the Stata file. This is a missing value that should be NA. For example, consider the variable 'm1b9b11' for the person with challengeID 1104. For more on labelled and as_factors, see the documentation of haven.ДЄnother thing you will notice is that some of the missing data codes from the Stata file donвЂ™t get converted to NA. To convert labelled to factors, use as_factor (not as.factor). One you start working with ffc.stata, one thing you will notice is that many columns are of type labelled, which is not common in R. csv file too so that we can compare them):ДЇfc.stata <- read_dta(file = 'background.dta')ДЇfc.csv <- read_csv(file = 'background.csv') In this post IвЂ™ll use haven because it is part of the tidyverse.

If you have questions-and suggestions-please feel free to post them at the bottom of this post.

So, in this post, IвЂ™ll give some pointers to getting up and running with the. dta format is native to Stata, and you might prefer to use R. dta format, which means the files now include metadata that was not available in the. WeвЂ™ve just released the Fragile Families Challenge data in.
