read_sav() reads both
.zsav files when
compress = TRUE.
read_spss() uses either
read_sav() based on the
read_sav( file, encoding = NULL, user_na = FALSE, col_select = NULL, skip = 0, n_max = Inf, .name_repair = "unique" )
read_por( file, user_na = FALSE, col_select = NULL, skip = 0, n_max = Inf, .name_repair = "unique" )
write_sav(data, path, compress = c("byte", "none", "zsav"))
read_spss( file, user_na = FALSE, col_select = NULL, skip = 0, n_max = Inf, .name_repair = "unique" )
Either a path to a file, a connection, or literal data (either a single string or a raw vector).
Files ending in
be automatically uncompressed. Files starting with
ftps:// will be automatically
downloaded. Remote gz files can also be automatically downloaded and
Literal data is most useful for examples and tests. To be recognised as
literal data, the input must be either wrapped with
I(), be a string
containing at least one new line, or be a vector containing at least one
string with a new line.
Using a value of
clipboard() will read from the system clipboard.
The character encoding used for the file. The default,
NULL, use the encoding specified in the file, but sometimes this
value is incorrect and it is useful to be able to override it.
TRUE variables with user defined missing will
be read into
labelled_spss() objects. If
default, user-defined missings will be converted to
One or more selection expressions, like in
list() to use more than one expression.
?dplyr::select for details on available selection options. Only the
specified columns will be read from
Number of lines to skip before reading data.
Maximum number of lines to read.
Treatment of problematic column names:
"minimal": No name repair or checks, beyond basic existence,
"unique": Make sure names are unique and not empty,
"check_unique": (default value), no name repair, but check they are
"universal": Make the names
unique and syntactic
a function: apply custom name repair (e.g.,
.name_repair = make.names
for names in the style of base R).
A purrr-style anonymous function, see
This argument is passed on as
See there for more details on these terms and the strategies used
to enforce them.
Data frame to write.
Path to a file where the data will be written.
Compression type to use:
"byte": the default, uses byte compression.
"none": no compression. This is useful for software that has issues with
.sav files (e.g. SAS).
"zsav": uses zlib compression and produces a
.zsav file. zlib
compression is supported by SPSS version 21.0 and above.
FALSE can be used for backwards compatibility, and correspond
to the "zsav" and "none" options respectively.
A tibble, data frame variant with nice defaults.
Variable labels are stored in the "label" attribute of each variable. It is not printed on the console, but the RStudio viewer will show it.
write_sav() returns the input
Currently haven can read and write logical, integer, numeric, character
and factors. See
labelled_spss() for how labelled variables in
SPSS are handled in R.
