linechart object

Creation of a linechart object that can be inserted in a 'Microsoft' document.

In a line chart, category data is distributed evenly along the horizontal axis, and all value data is distributed evenly along the vertical axis. Line charts can show continuous data over time on an evenly scaled axis, so they're ideal for showing trends in data at equal intervals, like months and quarters.

ms_linechart(data, x, y, group = NULL, labels = NULL, asis = FALSE)

Arguments

data

a data.frame

x

x colname

y

y colname

group

grouping colname used to split data into series. Optional.

labels

colnames of columns to be used as labels into series. Optional. If more than a name, only the first one will be used as label, but all labels (transposed if a group is used) will be available in the Excel file associated with the chart.

asis

bool parameter defaulting to FALSE. If TRUE the data will not be modified.
