The goal of the comparison operators is to return a TRUE or FALSE value when any two objects are compared. The operators provides a simple, reliable equality check that allows comparing of NULLs, NA values, and atomic data types without error. This operator performs a greater than comparison.
For data frames, the operator will compare all values in all columns, and return a single TRUE if all values in the second data frame are greater than the corresponding values in the first data frame.
x1 %gt% x2
x1 |
The first object to compare |
x2 |
The second object to compare |
A single TRUE or FALSE value indicating the results of the comparison.
Other operators:
%eq%(),
%ge%(),
%le%(),
%lt%(),
%ne%(),
%p%()
# Comparing of NULLs and NA
NULL %gt% NULL # FALSE
NULL %gt% NA # FALSE
NA %gt% NA # FALSE
1 %gt% NULL # FALSE
1 %gt% NA # FALSE
# Comparing of atomic values
1 %gt% 1 # FALSE
2 %gt% 1 # TRUE
1 %gt% 2 # FALSE
"one" %gt% "one" # FALSE
1 %gt% "one" # FALSE
1 %gt% Sys.Date() # FALSE

# Comparing of vectors
v1 <- c(0, 1, 2)
v2 <- c(1, 2, 3)
v3 <- c(2, 3, 4)
v1 %gt% v1 # FALSE
v1 %gt% v2 # FALSE
v2 %gt% v1 # TRUE
v3 %gt% v1 # TRUE
# Comparing of data frames
d1 <- data.frame(A = v1, B = v2)
d2 <- data.frame(A = v2, B = v3)
d1 %gt% d1 # FALSE
d1 %gt% d2 # FALSE
d2 %gt% d1 # TRUE
# Mixing it up
d1 %gt% NULL # FALSE
v1 %gt% d1 # FALSE
1 %gt% v1 # FALSE
