findCompoundsByName {ChemmineR} | R Documentation

## Find compound by name

### Description

Find the ids of compounds given the names.

### Usage

    findCompoundsByName(conn, names, keepOrder = FALSE, allowMissing = FALSE)

### Arguments

`conn` | A database connection object, such as is returned by `initDb`.
`names` | A list of names of compounds to search for. The names are those that would be returned by `sdfid`. An error will be raised if any names are not found.
`keepOrder` | If true, the order of the output compound ids will be the same as the input names. This imposes a performance hit that can be significant for large datasets, thus it should be left FALSE unless needed.
`allowMissing` | When this is false an error will be raised when names queried were not found in the database. If true, just those that are found will be returned with no error or warning.

### Value

Returns the compound ids for compounds with the given name. The output order is not guaranteed unless keepOrder is set to TRUE. An error will be raised if any name cannot be found.

### Examples

       #create and initialize a new SQLite database
       conn = initDb("test4.db")

    	data(sdfsample)

    	#just load the data with no features or descriptors
    	ids=loadSdf(conn,sdfsample)

       # find id of compound 650003
       findCompoundsByName(conn,c("650003"))
    	unlink("test4.db")
