here is the data, and the deadline is Oct. 20:00pm (EST). Thank you.

Ok thanks,

Just two questions.

Did you mean October 20?

Are there any specific questions that need to be answered through the data analysis or a description of the data?



Customer: replied 9 months ago.
I mean Oct 19,20:00pm(EST). please answer all the question on R attachment.

Ok. But I have only received node.docx and data 1.docx and there are no questions in them just data.

Here is the problem

Ok thank u

Just a status update. I am doing the pie charts.

I am not sure about number 2, if you understand what it wants you can break it down then I'll put it in code


#Number 1

links <- read.csv("links.csv")
nodes <- read.csv("nodes.csv")

# Number 2
nrow(nodes); length(unique(nodes$id))
nrow(links); nrow(unique(links[,c("source", "target")]))


# Number 3

# In-degree
degree(net, mode="in")

# Out-degree
degree(net, mode="out")

# Number 4

net <- graph_from_data_frame(d=links, vertices=nodes, directed=T)
net <- simplify(net, remove.multiple = F, remove.loops = T)
deg <- degree(net, mode="all")
V(net)$size <- deg*3
# Set edge width based on weight:
E(net)$width <- E(net)$weight/6
E(net)$width <- 1+E(net)$weight/12
l <- layout.bipartite
plot(net, edge.arrow.size=.4, layout=l)

sorry,I do not know how to do number

Ok I think I get it after reading it multiple times. The structuring of the sentence there is just not clear its joined 'and' too many times.

# Number 5. 1 a)

age_calc <- function(b_year){
start <- b_year
end <- 2016
result <- end - start

ages = lapply(E(net)$birth_year, age_calc);
df=data.frame(id=paste('R',seq( ),sep=''),value=as.numeric(c(ages)))

# making groups

# calculating %ages for slice

perct <- round(slice/sum(slice)*100)
lbls <- c("under 30", "30 to 50", "Over 50")
lbls <- paste(lbls, perct)
lbls <- paste(lbls,"%",sep=" ")
# make pie

# Number 5. 1 b)
mytable <- table(E(net)$gender)
lbls <- c("Males", "Females")
pct <- round(mytable/sum(mytable)*100)
lbls <- paste(lbls, pct) # add percents to labels
lbls <- paste(lbls,"%",sep="")
pie(mytable, labels = lbls, main="Gender")
