Description Usage Arguments Details
This method implements a sorted of methyl-eQTL with a formula specified as:
1 | mclust.lm.X(formula, covs, meth, X, gee.corstr = NULL, ..., mc.cores = 4)
|
covs |
covariate data.frame containing the terms in formula except "methylation" which is added automatically |
meth |
a list of matrices of correlated data or a single methylation matrix |
formula |
an R formula containing "methylation" |
X |
a matrix with columns matching those in meth.
n_probes X n_samples. Each row is tested by modifying
|
gee.corstr |
if specified, the the corstr arg to geeglm. |
mc.cores |
the number of processors to use if meths is a list of matrices to test. |
... |
arguments sent to |
methylation ~ disease + age
each row in X
is inserted into the model and tested
so the model would be:
methylation ~ X[irow,] + disease + age
and the reported coefficent and p-value are from the X[irow,] covariate. This allows one to test a number of expression probes against a (number of) cluster of correlated methylation probes. Though we could also use this to test, for example a set of methylation probes against every OTU in a microbiome study. In this way, we could find DMRs related to the microbiome.
