pillar-stats | R Documentation |
For an ijtiff_img-style array img
(indexed as img[y, x, channel, frame]
), pillar xy
of channel
ch
is defined as img[y, x, ch, ]
. These functions compute the mean,
median and variance of each pillar for each channel.
sum_pillars(img, parallel = FALSE) mean_pillars(img, parallel = FALSE) median_pillars(img, parallel = FALSE) var_pillars(img, parallel = FALSE)
img |
A 4-dimensional array in the style of an
ijtiff_img (indexed by |

Would you like to use multiple cores to speed up this
function? If so, set the number of cores here, or to use all available
cores, use |
An ijtiff_img-style array arr
with one frame.
arr[y, x, ch, 1]
is equal to mean(img[y, x, ch, ])
, median(img[y, x, ch, ])
, or var(img[y, x, ch, ])
.
aaa <- array(seq_len(2^4), dim = rep(2, 4)) # a 2-channel, 2-frame array sum_pillars(aaa) mean_pillars(aaa) median_pillars(aaa) var_pillars(aaa)
