'which' command in R with case insensitive

You can index it with grepl by using the argument

x <- c("col7", "COL73", "Col17",
"CoL73", "cOl73")
grepl("col73", x,

Similarly, grep returns the numeric index

grep("col73", x,
# [1] 2 4 5

For data frame column subsets

df[grepl("col73", names(df),]

How to create a case insensitive Regexp from a non-case insensitive Regexp?

Case Insensitive String Array Comparison
Your code wont compile as you are not overriding the Object's equals method which has signature like public boolean equals(Object obj) Also to do comparison, you could do the following in your modified equals as below: if (array == foo.array) { return true; } if (array == null || foo.array == null) { return false; } int length = array.length; if (foo.length != length) return f

Case-insensitive primary key of type nvarchar where ß != ss
The closest I can get to a workaround is using an indexed view to add a unique constraint on UPPER(ID) to stop primary key violation that is not picked up by the binary collation used on the actual primary key, e.g. CREATE TABLE CollationTest ( ID NVARCHAR(50) COLLATE Latin1_General_BIN NOT NULL, CONSTRAINT PK_CollationTest_ID PRIMARY KEY (ID) ); GO CREATE VIEW dbo.CollationTestConst
