HTML.data.frame {R2HTML} | R Documentation |
Write a data.frame (or matrix) to a HTML output
Description
This function exports a data.frame to a HTML file. Many arguments allow to customize the layout of the HTML table.
Usage
## S3 method for class 'data.frame'
HTML(x, file = HTMLGetFile(),
Border = 1, innerBorder = 0, classfirstline = "firstline",
classfirstcolumn = "firstcolumn", classcellinside = "cellinside",
append = TRUE, align = "center", caption = "", captionalign = "bottom",
classcaption = "captiondataframe", classtable = "dataframe",
digits = getOption("R2HTML.format.digits"),
nsmall = getOption("R2HTML.format.nsmall"),
big.mark = getOption("R2HTML.format.big.mark"),
big.interval = getOption("R2HTML.format.big.interval"),
decimal.mark = getOption("R2HTML.format.decimal.mark"),
sortableDF = getOption("R2HTML.sortableDF"), row.names = TRUE, ...)
Arguments
x |
a data.frame |
file |
target HTLM output |
Border |
the size of the border around the table. Could be 0,1,... but also NULL |
innerBorder |
the size of the border inside the table - see details |
classfirstline |
CSS class for the first line (header - variable names) |
classfirstcolumn |
CSS class for the first column (rownames) |
classcellinside |
CSS class for others cells |
append |
logical. If 'TRUE' output will be appended to 'file'; otherwise, it will overwrite the contents of 'file' |
align |
alignment to be used: center, left or right |
caption |
optional caption to append to the table |
captionalign |
alignment to be used for the caption: could be bottom or top |
classcaption |
CSS class to use for caption |
classtable |
CSS class to be used for the whole table (in html <table> statement) |
digits |
number of digits to use for rounding |
nsmall |
number of digits which will always appear to the right of the decimal point in formatting real/complex numbers in non-scientific formats. Allowed values '0 <= nsmall <= 20' |
big.mark |
character; if not empty used as mark between every 'big.interval' decimals before (hence 'big') the decimal point |
big.interval |
see 'big.mark' above; defaults to 3 |
decimal.mark |
the character used to indicate the numeric decimal point |
sortableDF |
See details |
row.names |
logical. If 'TRUE' row.names are shown in the output; otherwise they are omitted |

Details
For the moment, HTML.matrix
and HTML.data.frame
do have the same options.
Tables are build using two different HTML tables, one beeing encapsulated within the other, which allows to have a table without borders inside but with a border outside. It is nevertheless recommended to rely on CSS to obtain such results...
Now format
is called to format numerical values (modif. suggested by Arne Henningsen). The corresponding arguments are: digits
, nsmall
, big.mark
, big.intervall
and decimal.mark
. For each argument, one can supply either a single value or a vector. In the second case, the size of the vector has to be the number of columns of the data.frame and formatting options will be used element-wise (column by column).
Some options are used to pass default values.
You can see those options with (by example):
getOption("R2HTML.format.decimal.mark")
and options("R2HTML.format.decimal.mark"=",")
Sortable data.frame uses a DHTML behavior. This requires the file ‘tablesort.htc’ which comes with R2HTML to be placed in the same directory than the output. This functionality only works for HTML files located on a web server (not on local computer).
Value
no value returned.

Examples
tmpfic=HTMLInitFile(tempdir(),CSSFile=system.file("samples", "R2HTML.css", package="R2HTML"))
data(iris)
HTML(as.title("Fisher Iris dataset"),file=tmpfic)
HTML(iris, file=tmpfic)
# File is generated, you can call the browser:
## Not run: browseURL(tmpfic)
# Export one line of iris using default decimal separator
HTML(iris[1,],file="")
# Seeing default decimal separator:
getOption("R2HTML.format.decimal.mark")
# Modifying it:
options("R2HTML.format.decimal.mark"=",")
HTML(iris[1,],file="")
# Bypassing value set in option:
HTML(iris[1,],file="",decimal.mark="*")
# Using a vector for formatting options
HTML(iris[1:2,1:2],nsmall=c(3,1),file="")
