report.quanti

0th

Percentile

Creates a desc object of "quantitative" statistics

report.quanti Returns quantitative descriptive statistics such as mean, median, standard deviation etc...

Usage
report.quanti(data, y, x1 = NULL, x2 = NULL, y.label = y,
  round = 2, total = F, scientific = F, digits = NULL,
  at.row = NULL, subjid = NULL, geomean = F)
Arguments
data

Data.frame object

y

Character indicating a numerical vector in the data frame passed to data argument

x1

Character indicating a factor in the data (levels will be displayed in columns)

x2

Character indicating a factor in the data (levels will be displayed in lines)

y.label

Character. Indicates the label for y parameter

round

Numeric to indicate how to round statistics

total

Logical to indicate if a "Total" column should be added

scientific

Logical to indicate if statistics should be displayed in scientific notations

digits

Numeric (used if scientifc=T) to indicate how many digits to use in scientific notation

at.row

a character. Used to space the results (see example below)

subjid

Character. Indicates the column in which there is the subject Id to add the number of subjects in the column header if x1 and x2 are not null.

geomean

Boolean. If yes geometric mean is calculated instead of arithmetic mean: (exp(mean(log(x),na.rm=T))) fpr x>0

Details

This function computes and reports quantitative statistics on y. And can gives the statistics by level of two factors (x1 in columns and/or x2 in rows). See the example to show the results. If total=T, the last column is the statistics performed overall levels of x1 for each levels of x2. Quantiles are calculated using type 3 (SAS) algorithms.

"geomean" compute the geometric mean defined as exp(mean(log(y))). The values below or equal 0 are removed and a message is printed to indicate how many values were deleted to calculate the geometric mean.

N returns the number of observations (including NA values)

Value

A desc object.
