animateLinkage(linkage, input.param, input.joint=NULL,
               check.inter.joint.dist = TRUE, check.joint.cons = TRUE, 
               check.inter.point.dist = TRUE, print.progress = FALSE)

`linkage`	A linkage object. This is a list of class `"linkage"` created by `defineLinkage`.
`input.param`	A list containing the input parameters for the linkage. The number of list elements corresponds to the number of joints for which input motion is specified. Thus, a one degree-of-freedom mechanism should be of length one; a two degree-of-freedom mechanism of length two, etc.
`input.joint`	A vector specifying the joint(s) at which the input motion is to be applied. Currently, input motion can only be specified at grounded joints.
`check.inter.joint.dist`	A logical indicating whether a check should be run to verify that the distances among connected joints is constant. A warning message is displayed if the distances are non-constant.
`check.joint.cons`	A logical indicating whether a check should be run to verify that the joint constraints are maintained through the simulation. This feature is currently in development and does not work for all joint types.
`check.inter.point.dist`	A logical indicating whether a check should be run to verify that the distances among points on the same body are constant. A warning message is displayed if the distances are non-constant.
`print.progress`	A logical indicating whether to print progress while running.

Please see linkR Resources for a tutorial on how to use the linkR package and the linkR example gallery for several examples (code and animations) of different linkages that can be created using linkR.

a list of class "linkage" having the same elements as the input linkage with some exceptions, including:

`joint.coor`	The joint matrix will be converted to an array, where `dim(joints)[3]` is equal to the number of animation iterations.
`points`	If provided in the input, the point matrix will be converted to an array, where `dim(points)[3]` is equal to the number of animation iterations.
