长型数据到宽型数据的转换,在reshape2中没有cast函数,根据处理数据的不同类型,用acast(vector/matrix/array)和dcast(dataframe)函数取代。 这里我们的数据是数据框,因此使用dcast函数,其中的公式跟cast类似。 (widedata2 <- dcast(longdata2,ID+Time~variable)) (widedata2 <- dcast(longdata2,ID~Time+variabl...

Converting a JSON File to a Data Frame To convert JSON file to a Data Frame, we use the as.data.frame() function. For example: library("rjson") newfile <- fromJSON(file = "file1.json") #To convert a JSON file to a data frame jsondataframe <- as.data.frame(newfile) print(jso...

parser.parse_file("dataframe.rds") data = rdata.conversion.convert(parsed) would be data = rdata.read_rds("dataframe.rds") And maybe also a read_rda. A single read_rdata can do for both cases but that does not communicate the difference between reading an object vs an environment with...
.RData 数据导入python,转化成dataframe,numpy array,dict 1.安装rpy2 及注意细节: python 读.RData数据的包有两个:rpy2 和 pyreadr。 pyreadr提供了四个函数,可以对一些简单的RData 和 python 数据之间进行转换,如 下图。但是如果你需要导入的数据并非以下格式,如list,array等,请考虑使用rpy2。
