Hi Grace, Next time, could you use dput() to make a _small_ reproducible example? Editing out all the symbols added by your mailer and command prompt takes quite some time.

Example: For a=3, we can find only 2 orthogonal contrasts. Any other Helmert contrasts: Each level of a factor is compared to the mean of subsequent o A sensitivity analysis can be used to investigate the impact of outliers. • The Prime numbers are numbers that have only 2 factors: 1 and themselves.

In the following examples, OP passed the name of their variables rather than their values to lm. Since a name is a single value character, it is later coerced to a single-level factor and causes the error. As the Posting Guide directs, please make all replies to the list. Basically, you need to inspect your data.
