addGeneFeatures | R Documentation |
This function allows to savely add features to the gene meta data.frame of an expression matrix of choice.
addGeneFeatures(
object,
gene_df,
feature_names = NULL,
mtr_name = NULL,
overwrite = FALSE,
verbose = NULL,
of_sample = NA
)
object |
A valid spata-object. |
gene_df |
A data.frame that contains the variables specified by name
in the argument |
feature_names |
Character vector or NULL. See details for more. |
mtr_name |
Character value. The name of the matrix of interest. |
overwrite |
Logical. If the specified feature names already exist in the current spata-object this argument must be set to TRUE in order to overwrite them. |
verbose |
Logical. If set to TRUE informative messages regarding the computational progress will be printed. (Warning messages will always be printed.) |
of_sample |
This argument is currently inactive. It might be reactivated when spata-objects can store more than one sample. |
If you are only interested in adding specific features to the spata-object
you can specify those with the feature_names
-argument. If no variables
are specified this way all variables found in the input data.frame for argument
gene_df
are taken. (Apart from the key variable genes).
Eventually the new features are joined via dplyr::left_join()
over the
key-variables genes. Additional steps secure
the joining process.
The input spata2
object containing the added or computed
results.
