我有一个带有列名和行名的数据框。我试图用write.csv和write.table保存数据帧，但是当我在excel中打开csv文件时，列名称的行就在更多行上。如果我在R中重新加载数据帧时没有其他问题，这对我来说并不代表问题。如果我设置header = FALSE，则会发生read.csv重新加载数据的情况，如果我使用header = TRUE，则当我使用view（）时，数据帧看起来还不错。但是，如果我尝试从中提取行，它总是给我第一行（带有列名的行）。我试图将列名保存在向量中，从数据集中删除该行，并使用colnames（df）= ..重命名它，但是它不允许我重命名。我能做什么？首先，我上传了一个csv文件，并对其进行了一些操作]
data = read.csv("movie.csv",header=TRUE)
#head(data)
attach(data)
bipartite_network=data[,c("director_name","actor_1_name","actor_2_name","actor_3_name")]
d1=data[,c("director_name","actor_1_name")]
d2=data[,c("director_name","actor_2_name")]
d3=data[,c("director_name","actor_3_name")]
names(d1)=names(d2)
names(d3)=names(d2)
network=rbind(d1,d2)
network=rbind(network,d3)
network=distinct(network)
actors=as.data.frame(network[,2])
actors=distinct(actors)
dim_col=dim(actors)[1][1]
directors=as.data.frame(network[,1])
directors=distinct(directors)
dim_row=dim(directors)[1][1]
adj_matrix=matrix(0,dim_row,dim_col)
colnames(adj_matrix)=actors[,1]
rownames(adj_matrix)=directors[,1]
for(i in 1:(dim(network)[1])){
adj_matrix[network[i,1],network[i,2]]=1
}
# count=0
# for(i in 1:dim(adj_matrix)[1]){
# for(j in 1: dim(adj_matrix)[2]){
# if(adj_matrix[i,j]==1){
# count=count+1
# }
#
# }}
g=graph.incidence(adj_matrix,weighted = NULL)
csv_graph=as.data.frame(adj_matrix)
col_sums=colSums(csv_graph)
row_sums=rowSums(csv_graph)
reduced_graph=adj_matrix[!(row_sums<10),]
reduced_graph2=adj_matrix[,!(col_sums<5)]
reduced_graph2=t(reduced_graph2)
#eliminate missing value
reduced_graph=reduced_graph[,!(colnames(reduced_graph)=="")]
reduced_graph2=reduced_graph2[,!(colnames(reduced_graph2)=="")]
write.csv(reduced_graph2,"actor_director_reduced_network.csv",col.names = TRUE,row.names = TRUE)
write.csv(reduced_graph,"director_actor_reduced_network.csv",col.names = TRUE,row.names = TRUE)
但是保存后，如果我打开它，则会在下面的屏幕中看到所看到的内容：
然后：
network=read.csv("director_actor_reduced_network.csv", header=TRUE)
head(network)

[list output truncated]
您需要通过col.names=NA。
来自'write.table'帮助文件：
默认情况下，行名称的列没有列名。如果“ col.names = NA”和“ row.names = TRUE”，则空白列名称为添加了，这是读取CSV文件所使用的约定电子表格。
只是您需要学习/记住的R的这些怪癖之一。或每次都抬头（好像我似乎必须）。
========编辑========
您更新的说明表明您的电子表格可能无法正常工作。确保文件以“ .csv”扩展名命名，并且电子表格程序使用逗号分隔单元格。
如果这不起作用，我们将需要对问题进行更好的描述。
