# Argument Types Rasgo transforms use `type` within the `arguments` specification in each transform's YAML configuration file to trigger a user-friendly input in the UI. Here's a master list of the argument types that Rasgo supports:
| argument type | description | values | | ------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------ | | agg | Aggregation method | \[SUM, MIN, MAX, COUNT, MODE, AVG, MEDIAN] | | agg\_dict | A dictionary where one or more aggregations are provided for each column selected | | | boolean | A binary value | \[TRUE, FALSE] | | cast\_value\_dict | A dict where the keys are columns and the values are the new type to cast them to | | | column | A single column selector | | | column\_list | A selector for multiple columns | | | column\_value\_dict | Dictionary where a string value is provided for each column selected | | | conditional\_list | A nested list. In each inner list the first element would be the condition to check, and the second the value with which to fill | | | custom | The custom SQL transform template to apply | | | date\_part | a date part of a datetime value | \[DAY, HOUR, MINUTE, WEEK, MONTH, YEAR, QUARTER] | | datepart\_dict | dict where the keys are names of column(s) you want to datetrunc and the values are the desired date grain | | | imputation\_dict | Dictionary with keys as column names to impute missing values for, and dictionary values the type of imputation stratgey ('mean', 'median', 'mode', ) | | | int | A integer | | | int\_list | A list of integers | | | join\_dict | Columns to use for the join. Keys are columns in the source\_table and values are on columns in the join\_table | | | join\_type | Type of Join to use | \[LEFT, RIGHT, or INNER] | | math\_list | List of math operations to generate new columns. For example, \["AGE\_COLUMN + 5", "WEIGHT\_COLUMN / 100"] | | | mixed\_list | a list of strings, numbers, or column names | | | mixed\_value | a string, number, or column name | | | table | a Rasgo Dataset | | | table\_list | A list of Rasgo Datasets | | | timestamp | timestamp string | | | string | A string | | | string\_list | A list of strings | | | value | a string or number | | | value\_list | a list of strings or numbers | | | | | |
