从Web rbind日历数据-列表错误

Question

I am trying to import calendar dates in R. I found a website with dates that I imported with XML .

library('XML')
u="http://www.timeanddate.com/calendar/custom.html?year=2015&country=5&typ=0&display=2&cols=0&hol=0&cdt=1&holm=1&df=1"

tables = readHTMLTable(u)

Get rid of some unecessary elements

tables = tables[-1]
tables = tables[-1]
tables = tables[-13]

Generate list names

names(tables) <- paste('month', 1:12, sep = '')

with a solution proposed here

mtables = mapply(cbind, tables, 'Month'= 1:12, SIMPLIFY=F)

Here when I want to rbind my list:

do.call('rbind', mtables)

I get an error:

Error in match.names(clabs, names(xi)) :
names do not match previous names

Could you help with solve this error problem ?

Answer 1

rbind normally takes two parameters. here is a code snippet using rbind. hope this helps. cheers oliver

vehicles1 <- unique(grep("Vehicles", SCC$EI.Sector, ignore.case = TRUE, value = TRUE)) 
vehicles <- SCC[SCC$EI.Sector %in% vehicles1, ]["SCC"]

# Select observations relating to Baltimore MD
vehiclesBaltimore <- NEI[NEI$SCC %in% vehicles$SCC & NEI$fips == "24510",]

# Select observations relating to Los Angeles County CA
vehiclesLosAngelesCounty <- NEI[NEI$SCC %in% vehicles$SCC & NEI$fips == "06037",]

# Merge observations of Baltimore and Los Angeles County
vehiclesCompare <- rbind(vehiclesBaltimore, vehiclesLosAngelesCounty)

Answer 2

The issue was actually in the header .

`tables = readHTMLTable(u, header = F)`

instead of

`tables = readHTMLTable(u, header = T)` 

In order to get the same column names for each lists.

Thanks
