Function to add sample sizes to "size" compositions in a dataframe.
addSampleSizes(
dfr,
id.facs = NULL,
id.size = "size",
id.value = "N",
dfrSS = NULL,
id.ss = "ss",
verbose = FALSE
)
dfr |
- input dataframe with composition data by "size" and other factors |
id.facs |
- character vector of column names used as factors in calculating the sample sizes (or NULL) |
id.size |
- name of column in dfr with "size" data |
id.value |
- name of column in dfr with count data |
dfrSS |
- previously calculated dataframe with sample sizes by "other factors" (or NULL) |
id.ss |
- name of column in dfrSS with sample sizes |
verbose |
- flag to print diagnostic output to console |
Non-standard column names SHOULD NOT be back-quoted. If dfrSS
is
provided, it will be used as the source of the sample size information (useful
for appending modified sample sizes to size compositions); otherwise, "raw"
sample sizes are calculated directly from dfr
.
