Adjust the <code>sep<\/code> parameter accordingly if your data is separated by a different character.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I want to use a dictionary-like, like this:<br>Subject1<br>Item1:<br>Item2:<br>Subject2<br>Item1:<br>Item2:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you have a hierarchical structure where each subject has items underneath it, and you want to convert this structure into a table or a data frame, you can use a nested dictionary in Python. Here&#8217;s an example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>data = {\n    'Subject1': {\n        'Item1': None,\n        'Item2': None\n    },\n    'Subject2': {\n        'Item1': None,\n        'Item2': None\n    }\n}\n\n# Convert nested dictionary to a data frame\ndf = pd.json_normalize(data, sep='_')\n\n# Print the resulting data frame\nprint(df)\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">This will produce a data frame with columns like <code>Subject1_Item1<\/code>, <code>Subject1_Item2<\/code>, <code>Subject2_Item1<\/code>, <code>Subject2_Item2<\/code>. Each row will represent a combination of subject and item.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In R, you can achieve a similar result with a nested list:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>data &lt;- list(\n  Subject1 = list(Item1 = NULL, Item2 = NULL),\n  Subject2 = list(Item1 = NULL, Item2 = NULL)\n)\n\n# Convert nested list to a data frame\ndf &lt;- as.data.frame(do.call(rbind, lapply(data, function(x) unlist(x))))\n\n# Print the resulting data frame\nprint(df)\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">This will give you a data frame with columns like <code>Subject1_Item1<\/code>, <code>Subject1_Item2<\/code>, <code>Subject2_Item1<\/code>, <code>Subject2_Item2<\/code> in R.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Adjust the structure of the nested dictionary or list according to your specific hierarchy and data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you want the output to be a matrix where columns represent items and rows represent subjects, you can transpose the resulting data frame. Here&#8217;s how you can do it in both Python and R:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Python<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>import pandas as pd\n\ndata = {\n    'Subject1': {\n        'Item1': None,\n        'Item2': None\n    },\n    'Subject2': {\n        'Item1': None,\n        'Item2': None\n    }\n}\n\n# Convert nested dictionary to a data frame\ndf = pd.json_normalize(data, sep='_')\n\n# Transpose the data frame\ndf_transposed = df.transpose()\n\n# Print the resulting transposed data frame (matrix)\nprint(df_transposed)\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">R<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>data &lt;- list(\n  Subject1 = list(Item1 = NULL, Item2 = NULL),\n  Subject2 = list(Item1 = NULL, Item2 = NULL)\n)\n\n# Convert nested list to a data frame\ndf &lt;- as.data.frame(do.call(rbind, lapply(data, function(x) unlist(x))))\n\n# Transpose the data frame\ndf_transposed &lt;- t(df)\n\n# Print the resulting transposed data frame (matrix)\nprint(df_transposed)\nIn both cases, the resulting transposed matrix will have subjects as rows and items as columns. Adjust the code according to your specific data structure if needed.<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">In both cases, the resulting transposed matrix will have subjects as rows and items as columns.
