Description

• hm_cell or hm_index modify a data cell format (fmt="%s"), value (unnamed parameter) or style (text_align="left")

• hm_col or hm_row modify a row or column format (fmt="%s"), value (unnamed parameter) or style (text_align="left")

• hm_title modifies the title attribute of an html_matrix based on specific arguments

• hm_table modifies the properties of the entire HTML table within an html_matrix

• hm_tr modifies the properties of one or more table rows (tr elements) in an html_matrix. Row indices for modification (ind) can be specified along with additional parameters to customize the row format, values, or style

...

further elements

Examples

l <- html_matrix(matrix(1:6, ncol=2))
# replace l[1,1] by NA
hm_cell(l, 1, 1, NA)
# replace l[1,1] by NA and set the text_align to center
hm_cell(l, 1, 1, NA, text_align="center")
# replace l[1,3] and l[2,1] by NA
rcind <- cbind(c(1,3), c(2, 1))
hm_index(l, rcind, NA)
# set a new title
hm_title(l, "new title")
# set a new row or column title
hm_row(l, 2, "row 2")
hm_col(l, 1, "col 1")
# set fmt by column or row
print(hm_cell(l, fmt=c("%.0f", "%.1f", "%.2f"), byrow=FALSE), which="fmt")
print(hm_cell(l, fmt=c("%.0f", "%.1f"), byrow=TRUE), which="fmt")
