filterByTerm: Filter data frame by term
In ss-lab-cancerunit/SpiderSeqR: A Tool for Integration of Big Bio Data

Description Usage Arguments Value See Also Examples

Filter a data frame using full-text search within the data frame. If filter_columns are not specified, search will be performed within the whole data frame. If filter_columns are provided, search will only be limited to these columns. Full-text search works akin to searching within web search engines like Google. You can find out more about it here: https://www.sqlite.org/fts3.html (fts3 is used for consistency with fts search within the SRAdb database).

1	filterByTerm(df, query, filter_columns = NULL)

`df`	Data frame
`query`	Character string for fts search
`filter_columns`	Character vector with column names

A data frame subset according to query conditions

# Filter by 'TRIMKD' anywhere within df
df <- filterByTerm(df, "TRIMKD")
# NOTE: here (as is often the case), the study-level columns
# contain information pertaining to all samples and make finding relevant
# samples impossible

# Filter by 'TRIMKD' only within SRA_experiment_title column
df <- filterByTerm(df, "SRA_experiment_title: TRIMKD")
# NOTE: you can explore further possibilities by filtering by columns
# corresponding to different accession levels,
