R语言使用data.table包将dataframe宽表转化为长表(wide format to long format)、使用id.vars参数指定不变的列名称列表、使用variable.name指定原多个数据列名称生成的新数据列名称 library(data.table) long <- melt(setDT(wide), id.vars = c("Code","Country"), variable.name = "year") #其他方案...
rearrange a data frame from wide to long formatGiorgio Arcara
Now, we can use the melt function of the reshape2 package to convert our data matrix to long format: data_long1<-melt(data_wide,# Apply melt functionid.vars=c("ID1","ID2"))data_long1# Print long data# ID1 ID2 variable value# 1 A b x 1# 2 A c x 2# 3 B c x 3# 4 ...
Example 1: Reshaping Data Frame from Long to Wide Format Using reshape Function In Example 1, I’ll show how to convert a data frame fromlong to wide formatusing the reshape function. Within the reshape function, we have to specify the name of our data frame (i.e. data), the idvar ...

You want to do convert data from a wide format to a long format. Many functions in R expect data to be in a long format rather than a wide format. Programs like SPSS, however, often use wide-formatted data. Solution There are two sets of methods that are explained below: ...
This is to continue on the topic of using the melt/cast functions in reshape to convert between long and wide format of data frame. Here is the example I found helpful in generating covariate table required for PEER (or Matrix_eQTL) analysis: ...
