List unique values and count instances in .csv file
I need to take the second column of a .csv file and count the number of instances of each unique value in that same second column. I'd like the output to be value,count sorted by most instances. Thanks for any guidance!
Data example:
317476,317756,0
816063,318861,0
313123,319091,0
317020,318466,0
516779,166445,1

gldrawarraysinstanced
GLDRAWARRAYSINSTANCE(3G) OpenGL Manual GLDRAWARRAYSINSTANCE(3G)
NAME
glDrawArraysInstanced - draw multiple instances of a range of elements
C SPECIFICATION
void glDrawArraysInstanced(GLenum mode, GLint first, GLsizei count, GLsizei primcount);
PARAMETERS
mode
Specifies what kind of primitives to render. Symbolic constants GL_POINTS, GL_LINE_STRIP, GL_LINE_LOOP, GL_LINES, GL_TRIANGLE_STRIP,
GL_TRIANGLE_FAN, GL_TRIANGLESGL_LINES_ADJACENCY, GL_LINE_STRIP_ADJACENCY, GL_TRIANGLES_ADJACENCY, GL_TRIANGLE_STRIP_ADJACENCY and
GL_PATCHES are accepted.
first
Specifies the starting index in the enabled arrays.
count
Specifies the number of indices to be rendered.
primcount
Specifies the number of instances of the specified range of indices to be rendered.
DESCRIPTION
glDrawArraysInstanced behaves identically to glDrawArrays() except that primcount instances of the range of elements are executed and the
value of the internal counter instanceID advances for each iteration. instanceID is an internal 32-bit integer counter that may be read by
a vertex shader as gl_InstanceID.
glDrawArraysInstanced has the same effect as:
if ( mode or count is invalid )
generate appropriate error
else {
for (int i = 0; i < primcount ; i++) {
instanceID = i;
glDrawArrays(mode, first, count);
}
instanceID = 0;
}
ERRORS
GL_INVALID_ENUM is generated if mode is not one of the accepted values.
GL_INVALID_OPERATION is generated if a geometry shader is active and mode is incompatible with the input primitive type of the geometry
shader in the currently installed program object.
GL_INVALID_VALUE is generated if count or primcount are negative.
GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array and the buffer object's data store is
currently mapped.
