Hypothetical AB data
Description
Hypothetical data collected in an AB phase design with 27 measurement times.
Usage
data(AB)
Format
A data frame with 27 observations.
The first column contains the condition/phase labels ("A" and "B").
The second column contains the obtained scores.
The rows and columns are not labeled.

Examples
data(AB)
measure of effect size
Description
Calculates the specified effect size measure.
Usage
ES(design, ES, data = read.table(file.choose(new = FALSE)))
Arguments
design |
Type of single-case design: "AB", "ABA", "ABAB", "CRD"(completely randomized design), "RBD" (randomized block design), "ATD" (alternating treatments design), "MBD" (multiple-baseline AB design) or "Custom" (user specified design). |
ES |
Type of effect size that has to be calculated: "SMD" (standardized mean difference), "SMDpool" (pooled standardized mean difference), "PND+" / "PND-" (percentage of nonoverlapping data, depending on the expected direction of the treatment effect), "PEM+" / "PEM-" (percentage of data points exceeding the median, depending on the expected direction of the treatment effect), or "NAP+" / "NAP-" (nonoverlap of all pairs, depending on the expected direction of the treatment effect). |
data |
File in which the data can be found. Default: a window pops up in which the appropriate file can be selected. |
Details
When using the default 'data' argument, a window will pop up to ask in what file the data can be found. This text file containing the data should consist of two columns for single-case phase and alternation designs: the first with the condition labels and the second with the obtained scores.
For multiple-baseline designs, it should consist of these two columns for EACH unit. This way, each row represents one measurement occasion. It is important not to label the rows or columns.
Missing data should be indicated as NA
. For calculations, missing data are omitted.

Examples
data(AB)
ES(design = "AB", ES = "SMD", data = AB)
P-values
Description
Each p-value (i.e., each row) corresponds to one participant in the study.
Usage
data(P)
Format
A data frame with 7 observations on the following variable.
V1
P-value
Examples
data(P)
Statistical combination of p-values
Description
Calculates a general p-value by statistically combining the p-values of a number of independent studies, to determine whether a general significant result is obtained.
Usage
combine(method, pvalues = read.table(file.choose(new = FALSE)))
Arguments
method |
Indicates which combining function should be used: "x" (multiplicative) or "+" (additive) |
pvalues |
File in which the p-values can be found. Default: a window pops up in which the appropriate file can be selected. |
Details
When using the default 'pvalues' argument, a window will pop up to ask in what file the pvalues can be found. This text file containing the pvalues should consist of 1 column with all the obtained pvalues.
