lctran: Change the case of nmtran-like data items

Description

Previous data set requirements included lower case names for data items like AMT and EVID. Lower case is no longer required. However, it is still a requirement that nmtran like data column names are either all lower case or all upper case.

Usage

lctran(data, warn = TRUE)
uctran(data, warn = TRUE)

Arguments

data

A data set with nmtran-like format.

warn

If TRUE, a warning will be issued when there are both upper and lower case versions of any nmtran-like column in the data frame.

Value

A data frame with possibly renamed columns.

The input data set, with select columns made lower case.

Details

Columns that will be renamed with lower or upper case versions:

• AMT / amt

• II / ii

• SS / ss

• CMT / cmt

• ADDL / addl

• RATE / rate

• EVID / evid

• TIME / time

If both lower and upper case versions of the name are present in the data frame, no changes will be made.

Examples

# NOT RUN {
data <- data.frame(TIME = 0, AMT = 5, II = 24, addl = 2, WT = 80)
lctran(data)

data <- data.frame(TIME = 0, AMT = 5, II = 24, addl = 2, wt = 80)
uctran(data)

# warning
data <- data.frame(TIME = 1, time = 2, CMT = 5)
lctran(data)

# }
