R(20), Data Interface - Excel
package xlsx

if we wanna load the library xlsx
into R workspace, we need a Java environment. Otherwise, after run the command library("xlsx")
, we will see this:
Error: package or namespace load failed for ‘xlsx’:
.onLoad failed in loadNamespace() for 'rJava', details:
call: fun(libname, pkgname)
error: JAVA_HOME cannot be determined from the Registry

we can use input.xlsx()
to read the XLSX file. like:
# Read the first worksheet in the file input.xlsx.
data <- read.xlsx("input.xlsx", sheetIndex = 1)

To tell the truth, although I have already install Java environment in my environment, it still seems doesn't work. May be I will solve the problem in the future…
